The reason they all hate the Snake is because he lied to them, killed some of them, stole power from Death, and got them all tortured for a while. The only people who don't know about it are the newbies who show up after. And... let's be honest. That includes us. I had to learn it from the bells, too. Mr. Sss Sss wasn't about to tell any of us the details of that either.

But, there's a detail I think everyone has missed: when the Snake first bound Death, it made a bunch of lost souls Death was carrying get set free. Some of them even vanished into nothing.

...So...

Where did those souls come from?

The Snake said he honestly didn't know. In fact, some of them may be from rituals Blossom botched, or souls that 'didn't make it' here to the pasture when she summoned the bells that are here now.

If the Snake is right... then Blossom is objectively the real evil, no matter what the Snake has done. She's either bringing people here over and over to die, or killed off a lot of other people who were here to start with.

The problem will be convincing anyone that.
