I only watched the first couple seasons of The Boys (somehow less edgy than the comic book!)

But Huey slowly coming to the realization that sometimes the enemy can’t be defeated through the system and sometimes there are controlled opposition on “your side” working to just hinder your movement and you really do gotta come out and kill people sometimes.

Now it’s not him siding with the villains, so much as a liberal realizing the futility of non-violence and working within the system, and joining up with a guerilla terrorist group that eventually gets recruited by the CIA is surprisingly realistic for a superhero show made by Amazon.
