I have to say that I don't like the blame the victim mentality that shooters kill people that have been mean to them. I was bullied in middle school. Never once did it occur to me to kill all the other kids. It did occur to me to kill myself, which I think is pretty common.

If a woman's husband abuses her, would you blame her? Would you blame children for being abused? Say they "brought it on themselves"? Sadly, some people would. It's the same thing with these mass killings. Not all mentally ill people are dangerous, that is true. But there are sociopaths out there who don't care about other people. Being nice to them will not cure them.
