I think that's the awkwardness at the root of SU. There's no justice. I don't mean that in the THINK OF THE CHILDREN way, but the scale of slights and grievances is out of whack. That one human kid is bad for flirting or being too aggressive with it. Onions' dad is bad for being greedy or selfish, but then you have someone like the diamonds who torture thousands of their own and snuff out life on a galactic scale and they're redeemable.
