To give Kidds crew credit though, at least their loyal to his life. They sacrificed their gains, their poneglyph rubbings to try and save their captains and vice captains lives.
You can argue they betrayed Kidd and Killer and maybe Heat should have burned the rubbings or thrown them overboard but I think he made the right choice, especially from a more noble perspective, more selfless.
It's not worth throwing your lives away, "just for honour or pride" or whatever. Its a waste of life, especially when said captain is merely 23 or whatever, still barely an adult even, never mind living a full life and or many decades of adventure, sailing, exploring, fights, gains etc.
Kidds crew could have deserted him and fled. If they survive, they might anyway but I don't think they will. When you have someone as utterly loyal and selfless to his captain as Killer (like Kidds equivalent of Zoro), it sets a precedent to the rest of the crew and maybe inspires them to be loyal too.
His crew do seem ride or die but they could be dead here now too potentially and unfortunately.
If they do die, at least they died loyal to Kidd, as foolishly easily, young and thus inexperienced as they are.
