Are alchemical zombies evil?
Is their creation evil?
Alchemical Zombie - Benefit: The alchemist gains the ability to animate a relatively complete corpse as an alchemy-powered zombie. Zombies that are created in this manner count as undead created by animate dead for the purposes of determining how many undead the alchemist can control. The created zombie is a creature, not a supernatural effect.
I'm kind of assuming they are although it doesn't explicitly say so. If they are undead, and all undead are evil, then they would be evil. The more difficult question of course is if their creation is evil the way Animate Dead is an evil spell.
Animate Dead is an evil spell, using it is an evil act. Zombies have an alignment of "always neutral evil".
Alchemical Zombie says "counts as undead created by animate dead".
So, basically its the equivalent of the alchemist casting animate dead.
Edit: Just realized the ability doesn't specify it works like animate undead, only that they count for the purposes of control like animate dead. Still, I would say it's definitely evil.
