All terrorisms are evil. Even if it is any kind of reason, it is not justified. The person of a certain Muslim who commented on this video wrote it as follows.
“I am Muslim and I hate those who explode bombs in the name of Islam, I love Sweden despite military presence in Afghanistan, fortunately no one died”
I think that most Muslims agree with him. It solves no problem to use the bomb in a peaceful place. The criminal seems to have scuttled himself/herself, but he misunderstands it about a role of Swedish Afghanistan force.
And the freedom of expression must be respected. The Taliban ever destroyed a Buddhist image in large quantities. The outlook on self-righteous religion produces a collision by all means.
