What's the "worst" death in anime you've seen?

Primarily in terms of brutality or goriness, but it can be something simply rather depressing too. Basically, whatever you'd consider to be the 'worst' way to die, really.

I was just watching [DanMachi S4 Part 2 the other day, and one of the last few episodes got me thinking] >!when in Ryuu's flashback, the Juggernaut slaughtered the Astrea Familia. Some of the deaths in that got pretty grim, like when one of the girls gets her limbs cleaved off with her trying to frantically hit the big guy at the same time!<... It's not necessarily the absolute worst one I've seen (though it *is* one of the more depressing things I've seen in a little while), but it did make me think about it.
