First: Guilt.

He feels guilty for the events of past chapters. He did his best, but as you know, you cannot always save everyone. His guilt doesn't only come from feeling unprepared but also from his own attitude. Again, PKJ is doing a great job giving Damian personality while making him grow organically. He did something and he's facing the consequences of that. He was mean to someone unpromptedly and that person had an accident that he could have avoided but by being mean he also felt like he was responsible. This guilt is making him do things outside his regular personality. Is it bad? No, he's making changes for good without losing his personality but gaining new attributes and different ways of seeing the world.

Second: Growing, charitability?

Again, guilt is making him do things outside, but also reading about Thomas Wayne, a man who was well-known for helping others. This t the same it feels like this is a recon mission. Again very much Damian, doing certain things just to gather information but it feels like he's in a way understanding Thomas and his way of doing things. Damian has great traits that come from Ra's but combined with Thomas will make Damian a great person. (Ra's want a better world but his methods aren't the best but he does it for a better good.)

I really like this. Damian has never been a bad person but he had never gone to the point of helping outside the costume. He helps people but there's also that feel that he likes fighting (not killing) and the adrenaline and this change, feels like the better but it doesn't feel like he's gonna stop being sassy and snarky at points but a little more mindful of when he tends to be like that. Not a bad thing in my opinion but an actual natural growth and understanding from him.

Third: Accountability.

As he tries to mend his mistakes, the fact that for the first time, he's blaming Bruce for what happened to Alfred makes me so happy. He is taking accountability for his own actions when Bruce hadn't done the same, and he's learning not only from himself but from Bruce.

Damian is trying to learn what to do in his life, what he wants to do, not follow what Bruce does or what his mother and grandfathers (yes, plural) did, in a way it feels like leaving the mantle or stopping being a vigilante. He had died, he had seen things and it is understandable that at any point he questions everything and you know Bruce is not the best example, sometimes barely able to manage both lives and risking his life when he could just ask for help or when he needed rest and I wouldn't blame Damian if he wanted to have a healthy balance from both lives.
