In my country, punishments for killing people with deliberate violence varies from 8 months home detention (bus driver punched a passenger in the face, knocking him out so he fell backward and cracked his head on the ground), to several decades (man grabbed scissors from the kitchen, ran to his ex girlfriend's room, and stabbed her repeatedly). Both victims are equally dead but the courts decided that the perpetrators' feelings mattered far more than what they did. Perhaps if the bus driver had been weaker and needed a weapon, he'd be in prison for 10 years instead of free? Perhaps if the ex-boyfriend had used his fists outdoors on a concrete pavement, he'd be free? Seems grossly unfair.
