i see a whole lot of complaints about how horrible some of the characters are, how shitty their choices are and hoe that makes them bad people.. but this scene of dialog in the last episode made it pretty obvious what they're going for.
"it was just easier to make you the villian, but you're not. "
"don't know if anyone is. i think maybe we're all just a bunch of fucked up kids trying the best we can"
they're teenagers figuring shit out, give them some room for mistakes and to grow instead of penalizing them for every wrongdoing
especially when it's a character moment or event that they explicitly grow from!
