Oh for fuck's sake... Now you're blaming Tyrion for what happened to Sansa even though he wanted nothing to do with it and even offered Sansa to stop their marriage so she could marry someone she found more appealing? And even refused to touch her until she was ready and never once forced her to do anything? I don't blame Sansa at all but Tyrion was nothing but nice to her.

And yes, I think throwing a child out a window and breaking his spine is worse than what Tyrion did to Shae. If you're talking about threats now, Tyrion also threatened to put someone's child on a trebuchet so he's certainly not above that.
