Good OP!
It made good people I knew before they joined judgemental - or rarther their children judgemental and bigoted - they were raised that way, couldn't help it. But I knew that wasn't them deep down.
Some undoubtedly may have been slower to anger etc. But I think a lot of people hid their issues, instead of talking about It and getting help, addictions, porn, online gambling etc
As for me there is only *one thing* that has changed. I used to believe I would never kill under *any* circumstance, no matter who, mass murderer etc. Now I would. In order to protect my family, the innocent etc from someone attempting to take their life I would be prepared to take theirs.
Because I now know we get one chance, I view murder far more seriously...it's the ONLY thing you cannot make amends for or give back. So now, I believe in the severest penalties for murderer's and I would not hesitate to protect the innocent even if it means killing the criminal/terrorist/killer etc
I leave it to you whether you think me a better or worse person for it.
