I get ya, consequences but the whole thing was about their consequences already, doing what they do without ramifications, ignoring the fact if they didn't nothing it would be worse.
To answer some of your points, Cap only new (technically) that Hydra killed Iron Man's parents due to the conversation he had with Armin Zola, he didn't know directly that Bucky was involved.
Rhodes did have a big injury, not being able to walk and nearly dieing is a big thing. Black Goliath died at the hands of Thor bot in actual Civil War, he won't be back ever (not big enough of a character). Yet his fall is protected by his suit, it would contain most of the fall's impact.
Cap can do a lot and he only needed to counter the lift of that helicopter, okay so might not have happened in reality but you could see he was struggling.
Of course as a fanboy I have bigger issues of why Tony decided the death of 1 person was a concern suddenly (he happened to be american too) while saying this in front of Wanda who's brother died (in reality at his hands also if you take his 'guilt' in it all).
Hmm, pie.
