Okay, you got a point about Jason Todd. I think that was meant to be an Easter Egg though for comic readers, while those who are new just wouldn't know or care too much about that.

As with most of Suicide Squad, they didn't care about going depth to the characters. They were just gimmicks and nothing else, aside from the ones you mentioned and Will Smith (not calling him Deadshot).
