Active Shooter Situation at Ohio State

[Foxaèr]

It doesn't make me more angry, per se. Innocent lives being taken is horrendous regardless. But yes, it does make me a particular kind of irritated when we take someone in and they turn around and try to kill us.

To use an analogy, it's like... what's worse: Someone breaks into your house and kill your family? Or someone you take into your home to give shelter to the turns around and kills your family? 

Both our awful and infuriating, but the latter arouses a particular type of anger.

Your reasoning seems to come from a place of selfishness rather than a place of understanding. And that is sad.
