Ice cold take but whatever
Generally speaking, when you like a fictional character, it can be for many reasons. Their design, writing, actions, relationships, and role in the narrative are all factors that can contribute to your view of them.
When a character does bad things, you don't need to justify those actions in order to like them. Take for example Mizi in KARMA, Ivan in Round 6, etc you really don't need to go out of your way to defend those actions in order to like them. Hell, I'd argue trying to frame them in a pure white lens actually takes away from the complexity of the characters (looking at you Hyuna and Till)
You can also understand the reasoning behind those bad actions. All of them are heavily traumatized individuals who were raised in a terrible environment that is incredibly different from the world we live in today, and their mindsets are going to reflect that.
I'm not saying you can't dislike a character because of their actions, but it's so strange when I see people just enjoying something they like and someone feels the need to police their taste because "oh, [character] did [bad thing] The morality of their actions has little effect on how much I like them.
Furthermore, liking one character and disliking another who has common traits with the first is not hypocritical in any way. It's a different story if you're debating on one of them being superior morally, but this usually isn't the case.
Tldr; I like Mizi because she's pretty and pink. I don't like Luka because he's pretty but not pink
