Because everyone else...at least they tried. Didn't they? They tried. They didn't always treat them the way they think they wanted to be treated, the way that maybe they deserved, but they tried. Undyne gave them tea and flashed a broad, toothy grin, and Mettaton told them fondly to knock' em dead, darling, and Alphys apologized for everything she'd done, and Asgore fought so hard not to be backed into the corner he himself created.

They all hurt them. They all hurt them, but they all...tried.

They all tried.
