I just want to elaborate on one thing.
Jason Todd is not the temperamental one in the family
Yeah, sure, Jason is more serious and ruthless but the decisions he makes arent made out of anger or rage. He chooses his actions wisely out of his own beliefs. Such case is his decision to kill people that he feels deserve it. I understand how people may come to this conclusion but Jason isn’t fuelled by his rage.
Dick Grayson however, is.
He is more lighthearted than the rest of the batfamily, which can easily lead people to mischaracterise him as a bumbling ball of sunshine that adores hugs and cuddles. In the comics, someone once said something like: “He’s a happier, more approachable Batman” which is true, but people tend to forget that he is still like batman. (AKA not made out of sunshine and rainbows)
I’ve seen countless times where Dick loses his temper and lashes out, only to regret it later. Like when he beat the Joker to death, then later stared at his hands in shock saying “What have I done?” Or that time he snapped and went fucking crazy at Donna Troy. How about when he was trying to get a drink from a soda machine at Blüdhaven PD, and when it wouldn’t work, he punched it in anger, right in front of all his colleagues.
It was once stated while Dick was Damian’s Batman that sometimes he actively avoids human contact and watches nature documentaries because there aren’t any people in it.
The key difference between Dick and Jason here is that Jason doesn’t regret his actions as much, as he doesn’t usually lash out without thinking, while Dick does very frequently, as he has a nasty temper
