This gets into an interestingly philosophical question - I remember reading about a serial killer who seemed like he was also a genuinely good family man to his wife and kids. Does the fact he did committed pure evil now make him a bad husband and father? Obviously this is an extreme example, but somebody can be a crappy person in one way still have certain good qualities. Someone having other good qualities doesn't mean we shouldn't call out someone's flaws.
Also I will concede I don't personally Catturd nor know his life circumstances - judging from the outside is often unfair, but just his rhetoric on twitter about how he talks about Dems and turns everything into a conspiracy theory is offputting for me at least.
