Just because someone gets a little more angrier than.thers doesn't mean that they're a psychopath. The vast majority of people that get angry don't turn into hulk-mimicking rage machine that wrecks everything. Anger is an emotion and it's natural to feel it when you lose at something, people aren't emotionless but people have different thresholds for when a certain emotion is triggered. I play offline all the time, I don't get super salty - I travelled to a place knowing that I wouldn't be the best and got my assed whooped and didn't get angry. I would never hit someone, or break something that isn't mine.
We're talking about normal salt here, not people with a serious mental health issue. If someone is going to kill because of a loss then they have an issue and it should have been dealt with a while ago.
I did the same thing man, I was the guy in a team with people assigned to do different stuff, haha. Then I was the solo pub stomper, running around with the best guns/setup haha
Ah, the good old days... God I hate those game!
