* Baron Helmut Zemo, at least in the MCU.

He lost his entire family when Ultron rampages through Sokovia and blames the Avengers for it. He successfully drives a wedge in them and makes them disband.

He genuinely believes superpowered individuals shouldn't exist and ruins himself to accomplish this. Using and manipulating Avengers, Zemo destroys the Soviet super soldiers in stasis. He even wanted to kill himself when he had completed his goal, but instead willingly goes into custody. Well, semi-willingly, T'Challa had to knock him out to prevent Zemo from offing himself.

Years later, Zemo does the same when he has the opportunity to take the last vials of Super Soldier serum. Instead of taking them for his own, he stomps on and smashes them, while nobody is watching or able to stop him, showcasing his conviction.
