I feel sorry for Czar Alexander II. Try have a grain of human decency, and end up getting killed. He didn't have to stop and help innocent people wounded in the first attempt on his life. He could have just driven past, and that would have been the smart thing to do, but he chose to be a decent human being. And for that he ends up getting blown up to itty bitty pieces.
What sort of world is this? That people can think they can save the world by chucking a bomb at someone? At least if you're killing someone, have the decency to shoot him, and leave people who didn't have any political affiliations until you blew their legs off out of it.
