Never mind, I figured it out, I got the Azula mind break ending with -100 morality.
I'm still unsure on how to get Ty Lee to pee though, if she even can pee from what Ive seen on the slave route so far, someone in the comment section mentioned that the Main Character refused a pee scene because it was too evil, where or when does this scene happen? I never came across anything with choices and dialogue like that, even with good morality I could still do the Ty Lee pee drink scene, so it can't be that, what gives?
Someone also mentioned you can do stuff with Ty Lee on Ember Island, how? I wasn't able to get there on the slave route, is it even possible to go there on the slave route? What exactly am I missing?... this game is deep :3
