Pushing Bran out the window was shitty sure but he didn't have much of a choice
L M A O
I mean he had a choice but it was basically "kill kid" or "let Cersei and myself be executed"
1. There are infinite other options and 2. He was giddyabout it
1. Not really, is he gonna spy on the kid the rest of his life to make sure he doesn't tell anyone? 2. Not really. He made a sarcastic remark and that's it.
Like I said, it's shitty but there wasn't much else he could have done. He was apathetic at worst.
"Apathetic at worst" about killing a child = not dickish
