You are correct up to a point to draw parallels between the 2 atrocities.
But always remember: one was committed by an individual with psychological or depressive tendencies while the other is a whole worldwide program of thousands of people set up to talk other people into killing others on as large a scale as possible because they are non muslims, or should I say because be they are not of the same extreme brand of Islam as they are, and nothing deters them, even the possibility or high probability that they will be killing their own co religionists, and despite the fact that the very religion they claim to be acting on behalf of clearly says that killing anyone is clearly forbidden!
This said, the 2 tragedies are worlds apart.
