If people dont react on actions (no matter if good or bad - because we learn from both, but especially from bad things) then the species will stagnate and die too.
You obviously dont understand that we need to analyze such things to understand them. Just looking at the result and the nearest cause and reacting to that might be good enough as a 3 year old child in the sand box or for the lion thats hungry and runs off to kill something, or a man that beats his wife because she didnt make him dinner in time, but surely not for a social and complex species like us as a whole.
Bad things are a part of this world, and we learn from them by analyzing them thoroughly. If we dont, they will repeat themselves over and over again. If we keep let that happen, we dont have the right to call us an intelligent and adaptive race.
Waiting for BIS to come back to their senses and do a real ArmA 2 successor.
