1. Cap has never killed a Brainwashed solider as all of the 1940s Hydra Soldiers were in fact Nazis and the same can be said for most of the Modern Hydra solders as well.

2. He commit a War Crime by beheading that Flag Smasher while wearing the Symbol of the United States.

3. Except for the fact he could have said "No" to being Cap. He didn't had to be Cap.

Cap killed several Shield agents brainwashed by Loki in the first movie. Killing a terrorist isn’t a war crime. He literally explains why he said yes to being Cap. “Being Cap is the first time I had a chance to do something that actually feels right.”

1. Steve has never killed anyone that was brainwashed by Loki in the first, he just knocked them out just like the Other Avengers, Coulson, Maria, and Fury did.

2. The Flag Smasher was surrendering. You can't behead someone who was surrendering.

3. Stay as a Solider, Help the homeless, Help the people that was force out of their Homes. He didn't had to pick up the Shield lol.

I'm not trying to defend a terrorist but Karli at least had remorse or appeared to when talking to Sam before Walker showed up.

She did but all that was gone by the time of the final episode

No it wasn't because Sam defended her in a way with his speech saying none of that had to happen and wouldn't have if government had done better.

Sam defended her because of bad writing and he’s a hypocrite. Even Bucky was against his sympathy for Karli. Her remorse was totally gone. She tried to burn a van full of people alive

Only because (I think her reasoning earlier in the show applies here too) “this is the only language these people understand”.

What exactly makes him a hypocrite?

@Superbattleshipyamato please don’t defend/rationalize mass murder. Take note NONE of her followers approved of what she did. That wasn’t villain has a point, that was her jumping into insanity.

Additionally, their goal was to stop the vote, not murder the people. Karli did that on her own. She tried to kill the heroes multiple times without provocation.
