Killing people like that truck driver did is considered sin in Islam, I don't know where all you "blame Islam" get your facts from but I'm pretty sure you have never read the Quran in your life.
If Islam is the issue then when is the overwhelming majority of Muslims practicing its religion peacefully? why can't you find these "go kill some civilians" passages in the Quran?
R.I.P to the victims, god willing no more these attacks happen.
To deny Islam it a factor in these terrorist attacks is part of the problem.
