Which MCU villain would make a better Captain America...

The fascinating thing about this show is the (either intentional or unintentional) exploration of what makes a villain. Everybody loves Zemo, who has done much worse things than Walker. But they hate Walker because he's not Captain America. The character was set up for us to hate him, long before he killed anyone or even started talking sh*t with Sam and Bucky. He just went berserk and killed a terrorist (who IIRC moments earlier said he agreed with Karli killing innocent people in support of their ultimate goal) in retaliation for the murder of his partner. Zemo killed a lot of innocent people setting his plan in motion in CW, and arguably is the reason the Avengers split up, which allowed the snap to happen in the first place. But hey, give me an hour of him dancing in the club.

Everyone loves a charismatic villain, even if they know he's wrong. The jerk trying to do the right thing the wrong way is the guy we can't stand.
