[General Fantasy] Why do vampires bitch about the “curse of eternal life” and being unable to die when they can just walk out into the sun?

Walking out into the sun would be committing suicide, a bit no no in most religions, particularly Christianity.  If you're a vampire that's affected by crosses or holy water, then you can assume committing suicide would condemn you to hell, it's seen as a Mortal Sin.  Better to be undead and walk the earth than damn yourself to eternal suffering.
