I believe he kills at least one or two nameless criminals along the way as well. Not sure if the pencil trick man is dead, but I'm inclined to believe in the context of the movie he's supposed to be.

To your point though, there are no "innocent bystanders" killed by him. You still need to write out him trying to blow up the boats himself though, and if attacking a hospital is a war crime then I don't think blowing one up after making everyone evacuate is a good look for him either.
