May the innocent souls RIP.
It's not all Muslims involved in such terrorist activities and hence it's wrong to blame the entire community. I've heard of other religions too who take part in such activities as they are brainwashed. These terrorist groups kidnap children when they become 12-13 and keep provoking them to kill humans for their God and it's sad to see those kids being treated this way. The parents of such kids don't even get to meet their child and just see their child die due to these groups. It's the head of such terrorist groups who preach hate and evil. If they are executed, these activities would finally end.
