I love it when people take one look at Dick Grayson and Jason Todd, then interpret Dick's Robin as the happy one, and Jason's robin as the angry one, because you could not be any further away from the truth.
Jason was the kid who said that being Robin gave him magic and who probably said stuff like, "Being Robin motivated me to do all my homework!" or "Holy Molly". This man may be a crime-lord now, but he used to be such a goody two shoes.
Meanwhile, you have Bruce Wayne, first-time father, desperately trying to stop teeny tiny 8-year-old Dick from murdering/biting criminals in his tricolour costume and pixie boots. We are talking about the kid who was acting completely feral and who probably terrified goons for years. That kid had several intricate plans on how to torture and kill Tony Zucco.
