He has nothing to do with me and I wasn't even trying to imply he should be killed, just noting that there is clearly no working rehab type solution in place. Drugs and the continually increasing cost of living are only going to compound the problem. And I'm not so deluded to think I would be praised for murder. I'd have to be an extremist far right American politician or cop or something for that. I don't know where you get the idea of someone else doing it either.
Who can really judge anyone though. What is to stop a stabbing victim on an adrenaline rush from grabbing the blade, biting the hand holding it, and stabbing back repeatedly while screaming? Who's fault is it? When you are bleeding out after being stabbed do you need to feel sorry for the man stabbing you, and think about how he lived a hard life and was just down on his luck and had his mind repeatedly eroded by drugs after what was intended to be a brief respite from the difficulties of merely being alive and not birthed by at least moderately wealthy and mentally stable parents? Do you have to stop and think about whether it is wrong to kill and decide whether it would be better to bleed out alone and hope someone helps in time, or will he finish you off after your consciousness fades and run off with the $12.50 in your pocket and a stack of mostly useless cards?
That's only a theoretical case where both parties could be considered victims in some way. What about the famous serial killer that had an otherwise normal life and a family that was supposedly totally clueless and lived to a ripe old age before being caught? I seem to recall one or more cases of a man keeping a girl trapped in part of his house and raping her for years, somehow also without his family noticing. I don't really want to type in the search terms to try to find an article for that though. There are certainly no shortage of cases of people absolutely ruining the lives of others while living a life something like the American dream on the side.
If life was a video game you would probably go through a long journey to find the true villain that put everyone in the position, making friends along the way, questioning whether revenge would ease the pain or just make you feel empty, have some uplifting spiritual cleansing and the start of a romance, and then find out the real villains were legion but they were also all long dead and acting from beyond the grave. The systems they put in place had long normalized the suffering of all and contained sweet words and false promises that blinded people to the hypocrisies as they searched for an ultimately limited personal gain. Everyone comes together to change things for the better, but not enough people vote accordingly and they ended up losing rights previously earned through the sacrifices of their ancestors. The moral of the story is that life sucks and you die so forgive your murderers and give all your earnings to your corporate overlords.
