Bruce spent years after Endgame trying to build a normal life, make peace with himself, and actually control the Hulk. Then Jean takes over his body and forces all that old trauma back to the surface.
By the end, he’s back to Savage Hulk and ends up hospitalized for psychiatric help. Jean gets her redemption, but Bruce basically loses years of healing because of what happened to him. That’s honestly one of the saddest parts of the movie.
always check your own attitude too. it's not always the world around you, sometimes you are the toxic person. understand that you make mistakes and can hurt people. understand that there are things you need to work on. apologise, unlearn, and relearn, that's growth
just saw a video that said “no revenge because you’re gonna search for my heart in every person you meet, but you never gonna find it.” and it all makes sense
