Think they'll be much different?
At least if a normal behemoth rips out your heart, you won't turn into a murderous shadow monster or an emotionless shell.

Actually... I'm suddenly not quite sure which is worse; dying permanently, or becoming a killing machine but having the slim chance of being restored to your former self.
I have to say, I'm rather glad the Heartless didn't just kill me that night.

Huh...

Oh well. Heartless are still worse, if only because they reproduce like zombies.
