About stepping on people, I think I forgot to mention that ninjas would sometimes kill innocent people to get their disguise in order to get closer to their intended target.
Oh yeah, does anyone actually have a clue how ninjas actually operated? They weren't much of the "I'm going to run on rooftops, smash into their living room and then take out 10 samurais from the shadow". They were much more boring than that. They'd disguise themselves as one of the samurais, and kill the big cajuna when he's asleep and then just get out of the place. Sometimes some innocent people died so the ninja could get a proper outfit. Big deal, tyrants were killed, and so were some potential leaders.
If anyone ever played "Hitman", then basically you've got a good idea how ninja actually were.
Another note, most of the successful ninjas were kunoichi. It's a lot easier for a pretty girl to infiltrate

In my honest opinion, I think ninjas are not much different from any other assassin caste around the world. Heck, they're basically secret agents that infiltrate and mingle with the target and strike at his weakest moments.
Want to be impressed, research about the Hashasshin or something like that. Group of assassin originating from Baghdad, the original guys. They even invented the word Assassin.
