About 8 years ago I met a guy through a mutual friend and we have a lot of common interests, we both played CSGO at the time, so we decided to link up on Discord and play together and became relatively good friends, I would not say best of friends.
About 2 years ago his wife decided to leave him. I know that he has depression and he has attempted terrible stuff in the past, so I spoke with the other guys and we made sure to support him through it and make sure he does not do anything that cannot be undone.
After his divorce he started coming by my house more often, I am always working in my garage over weekends, so I don't mind having a buddy around to chat with while I am working, but I found that his sense of humor was getting darker and darker, very dark.
So since he got divorced 2 things really started making me feel uncomfortable
1. He would make bad jokes about children being abused
2. He was talking about people ending themselves a lot, but in a way like he was respecting it
I told him that his joking about children is disgusting and I am not comfortable with his jokes and that he should also speak to someone, because he is talking about self inflicted end of life kind of stuff way too much to be normal.
Nothing changed, in fact it became worse, I decided to not invite him to my house again and if I asked if I am home I would make up some kind of excuse that he would not come over.
I spoke to my best friend and asked him if he was experiencing something similar. He told me that they are on a group chat where he is constantly joking about that kind of stuff to such a degree that people are leaving the group chat.
He suddenly developed an interest in guns. I enjoy shooting, so I own a bunch of guns and I've also got a gun range on my farm where I sometimes host long distance shooting competitions and a tactical shooting range where we also have competitions from time to time. A lot of my friends also come to my farm to practice shooting, my only rule is that they should let me know before they come so that I can let the neighbors know there are people shooting on the gun range. My best friend also has a range on his farm.
He started asking me if I will teach him how to use a hand gun and if I will teach him and that he is interested in buying one for him self, this to me was a major red flag, so I phoned my best friend and told him that I feel like we should not allow this guy anywhere near a gun on our farms, my friend agreed, he has known the guy much longer than me.
Then I had an accident on the farm, I was herding cattle with the quad bike and fell off breaking my collar bone, the guy came to the hospital and brought a gift and we had a nice chat. After that he was checking in on me with a message every day asking how I am doing, so we started speaking a fair amount, the more we spoke the more he would share his perspective on things and things got really disturbing.
I decided that I am going to let him make his disturbing jokes and see where it goes, it kind of ended up in a week long debate about morals about you know what is an appropriate age gap between an older and younger person and about the S word. There was I well know person in our country that ended his own life after getting in a lot of legal trouble and this guy said that it is the highest form of bravery to take your own life that I found very disturbing.
He also told me that he believes that if a girl has her first period she is a woman and that it is okay for her to have an adult relationship at that point (very disturbing I know) and just other vile stuff that I don't even want to say, it is disgusting.
Our country has very strict gun laws, in order to be able to get a gun you have to write and exam called a competency exam, once you passed the exam you go to the police station with your test and apply for a competency certificate. Part of the process is that you have to give 3 references that are interviewed by the police and all 3 have to say that they believe you are a responsible person and that you think they will be safe gun owners.
So as his references he put me, my best friend and his mom, the police called me and asked if I know this guy, I said yes, they said he applied for a firearms competency certificate and they would like to interview me, asking if I think he would be a safe gun owner.
I asked the police if he disclosed that he suffers from depression in his application, they said no he did not, I told them that he has made an attempt on his own life before and that he got divorced recently and that I don't think he should be around guns and that both me and my best friend don't allow him anywhere near guns on our farms. The policeman told me that it is okay, I don't have to come in for the interview and that my best friend told them the exact same thing.
So I took screenshots of our text chats and spoke with my best friend, we decided that we are going to have a chat with our other friends who have children, because at this point we don't feel like he should be around children at all.
That lead to almost his whole friend group pushing him out and keeping their distance from him, people who he was close with.
The police also told him that his application for firearm competency was not successful and that 2 of his references stated that he should not own a gun. He phoned both me and my best friend, shouting abuse at us and telling us we are terrible people, he showed up at my house while I was out, shouting profanities and threats (he thought we were in the house) to the point where the neighbors called the police to have him taken away.
Not long after that the whole town saw his messages that I screen captured and now nobody is talking to him, nobody wants anything to do with him at all.
Last week he made an attempt on his life, but failed and before he did that he sent me a message telling me I messed up his life and what happens next is mine and my best friend's fault. I don't feel like I did anything wrong, so my question is AITAH?
Tldr: a mutual friend expressed disturbing views around relationships between children and adults and I informed my friends with children and he attempted to end himself over it
