Legally, he may have gone too far and may suffer manslaughter charges.
Personally? I honestly not going to pretend to care he shot the dude and even further, not going to lie that I don't derive a small bit of satisfaction from people who go around victimizing others facing consequences for their actions. You're 54 years old and stealing shyt. I mean, you can't even blame immaturity and young people's impulsivity on that. He was probably a lifelong scumbag and the world didn't become a worse place without him in it. Not going to pretend to care where folks who don't want to provide for themselves or take responsibility for their life and instead want to harm and victimize others and take their shyt or do harm to them. There are 6 billion people on this planet, not going to waste energy bleeding my heart over some dude who wasn't doing what he wasn't supposed to do, like taking care of his kids and family without resorting to crime, and end up fukking with the wrong one. These are the possible consequences. Teach your kids that this is the shyt that happens when you do shyt like this and maybe we can finally start dealing with fewer shytheads like this as a whole.
You dudes out here want to do crime and live the street life shyt but then want to cry and people to feel sorry when you meet street life consequences. fukk em.

At least he lived a long life relative to the average life span of people who chose this life style.
