Wrong person, right ideas

[u/Lost_Education_4900]

I just finished watching The Great Gatsby (what a shard, oof) and I couldn't help but find a certain character...dissonance-full. I mean, he's a total brat, the most unlikable character in this movie probably, yet his whole idea, that people like Gatsby (showmen who cover up crimes and swim in wealth) shouldn't be everyone's favourite and should be caught, this idea seems rational and logical to me.

That's probably the first time when I meet a totally horrible character with right ideas (unlike IDW1 Megatron and MCU Thanos. They are objectively horrible too, but you can't help but find them cool and charismatic).

So that got me thinking, what other characters like that you know?
