Least favorite ending?

This is probably a pretty cold take but the accomplice ending from 4.

It's creepy, dark, and interesting. But it makes 0 sense for your character to sacrifice the whole town including your 20-something other links and best friends you spent a whole year investigating with for the sake of one friend. The dude directly got your best friends love interest killed, indirectly almost got Nanako and most of the investigation team killed as well. But you bummed around with him at the mall a few times so let's forget all of that.

It feels as though the game itself actively discourages you from this ending as well lmao. You get like 2-3 chances to change your mind and when you side with him the game calls your decision monstrous.
