I think one of my favorite MCU moments was in Falcon and the Winter Soldier when Zemo destroyed the superserum vials instead of taking one for himself. Zemo isn't a hypocrite plotting to do the very thing he hates, like Killmonger. He isn't using a supposedly righteous cause to go on a power trip, like Thanos. We can agree or disagree with him, but Zemo does what he thinks is right because he thinks it's the right thing to do.
