A (very cute) dog who lives on the streets is being fed and trained. We don't see him again after those scenes but he is not harmed or killed! No worries
Before his mother is killed you see the officer press her against the wall and start to grope her thigh—she pulls out a knife and cuts him before he can go further.
spoiler:
a character gets her thumb cut off to use her fingerprint. shows it being separated with a platter, a couple times in bobby’s hand, then for the ID scan.
The main character’s whole motivation is the trauma he suffered as a kid from watching his mom get killed in front of him and his village burned down, and he has multiple flashbacks throughout the movie.
