Well... there have been a couple points in my life when I was a bit of a douchebag and thought that what's effectively rape would be fine against people who deserved it (meaning that I was just getting extremely angry at them). So... League of Legends was my life for like 2 years and I hated Lux. So I'd fantasize about raping her.
But you know, I'm a healthy functioning human being now who thinks that rape is a horrible, horrible thing that could be considered worse than death for some people, so... I don't really fantasize about rape anymore. I'm also much better at League and Lux's more annoying abilities are actually really easy to avoid if you can predict them.
But consentual hate fucking on the other hand, I could go for. See, it actually takes more effort to actively hate somebody than it does to just shrug them off or even love them to a certain extent. When you hate somebody, you think about them more than they people you love, and honestly, if you find each other attractive, why not go at if for a hate fuck where you basically insult each other at the same time. I'd honestly say most of-age tsundere characters fall into this pile.
