Considering the shit you have to pull to get Ophinia to go full laser-beam on you, she's not that far off.
Namely, you basically admit you're a horrible demon child, make a deal with the devil, rewind time and then have the gall to visit her without doing a pacifist run first.

Get dunked on, demon child.

Toriel has to watch. No reason.
Ophinia just likes it that way.

Truth be told.
I don't think she does.
Now she has a hole in her hideout.
Golly.

Jeepers, Ophinia looks evil. Though she's just super pissed at Frisk's rudeness. The evil spiel is just her having fun. She never did like that Angel of Death spiel. Being fake-evil is better!
I think golly might not cover it.
Gimme the hammer.
We're entering 'gosh' zone!
