Well if anything:

1. He killed you once. He can kill you again.

2. You'll be ressurrected as a grossly pink mockery of your original self, as a reminder of what happens to those who dare challenge the Murdercock Clan.

Do you even have the option to refuse his ressurrection? So he could potentially kill you then bring you back and let you go, but not before giving you a few turns of Gold Experience Requiem just to remind you who's boss, who can send you to hell before you die.

This is the only version of this meme i’ve seen that seems like it’s made by someone who’s actually watched Steven Universe.
It’s not that Steven is completely devoid of using force when he has to, he just wants people to better themselves. It’s his main combat mechanism since he was a small pudgy child since he really couldn’t “fight” anyone or anything then.
No one ever really pushes him that far though, so I’d say that’s more a flaw with the creativity of the plot than being a flaw with Steven, granted, every other character on the show is more than capable of killing if they really wanted to, so it’s not something the writers felt like needed to be explored.
