Of course he knew. He didn't intervene because he wanted Draco to make the decision not to be a killer and thus save his soul and most likely because he wanted Snape to kill him and be able to go under deep cover. I really don't think that part has anything to do with training Harry. It was Snape's job to prevent dangerous situations like with Katie and Ron or the DEs in the school. There were near misses, but they definitely tried.
