He killed his best friend in cold blood for selfish reasons. Up till then I was with you, but he made a choice when he killed Abner.
Cold blood? That certainly was NOT in cold blood. The definition of “cold blooded” according to Google is “(cold-blooded) cold: without compunction or human feeling”. It was written all over his face that he felt guilty for even considering killing his friend from the moment he showed up. If it was cold-blooded murder he would have stabbed him as soon as he set eyes on him. The fact that he didn’t means that he obviously had a LOT of “human feeling” towards his friend.
He didn’t want to kill him, obviously. It broke him to do so (which was Metatron’s plan. A broken soldier is the best kind) but he didn’t want to just give up on everything he stood for, everything he wanted and believed was right (restoring Heaven), especially not after all he’d already done. It’s a common theme in fiction, the whole “if I give up now the others will have died for nothing” thing.
Not to mention that it’s the only thing he wants. Gadreel will never be happy again until he is redeemed. He can’t live the life that Abner has chosen, he can’t just replace his family with another one. He loves the one he has too much for that. Then Abner tells him that "The key to happiness is getting the one thing you want most and never letting it go" and "There’s always a price. But it’s worth paying." Which is all the encouragement Gadreel needs that what he’s doing is right.
Also if you’re going to hate Gadreel for murdering a friend for selfish reasons I hope you also hate Lucifer for killing his brother Gabriel, Castiel for killing Balthazar, etc.
I don’t hate Gadreel at all, but I think he’s going to be a tough sell as a misunderstood innocent after this episode (9x10), which is where I saw him before this.
The definition of ‘in cold blood’ is to murder deliberately or in a premeditated fashion. Gadreel sat in Abner’s living room, talked with him and made a conscious decision to kill him in order to further his own agenda. That’s 1st degree murder in the US due to his conscious decision to kill, as opposed to a spontaneous murder.
Do I think Gadreel had conflict in his heart over murdering other angels? Absolutely — and kudos to Jared for playing him so well. But he made the DECISION to kill each one. And with Abner, he chose to murder someone who had only ever shown him kindness for his own personal gain — his place in Heaven. That, to me, is the definition of evil.
It’s been a tragic thing to me, watching a ‘good’ character make decisions that take him down a bad road, just like it was with Cas in season 6.
“Also if you’re going to hate Gadreel for murdering a friend for selfish reasons I hope you also hate Lucifer for killing his brother Gabriel, Castiel for killing Balthazar, etc.”
Lucifer — the embodiment of evil in the series.
Cas — killed Balthazar as the other angel was attempting to stab him. (Killed the other angels while under the influence of the Leviathans. Has admitted himself that he did horrible things and has attempted to repent them in various ways.)Source: kiterious
