How to unlock the Poetic Justice achievement in Castlevania: Harmony of Despair - Definitive Guide
The best place for this is on stage three, since there are loads of Imps there. They also respawn in a few spots, which gives you plenty of chances to try. Make sure to lure a single one away to a safe area, so that other enemies don't get in the way. Also, when attacking your possessed friend, try and use melee attacks. You don't want to accidentally hit the Imp! You can also make this easier on yourself, if you or your buddies happen to be wearing equipment which brings your defense too high. Either unequip your good armor before the stage starts, or just make sure that you let yourself get damaged to where your health is very low before the Imp possesses you.

Thanks to Seraphin Needed for pointing this out: Only female characters can be seduced to the Dark Side.

See the other solution for a much EASIER way to get this achievement.
Chapter 6: Dracula must be in his third form for this to happen. When in his third form, he will use a spell that casts out heart projectiles. Have a female character get hit with one of the hearts, which will result in the character attacking her allies and having a heart above her head. Quickly kill the character before the spell wears off. It's advisable for the female character to be weak for a quick kill.
Chapter 7: During the boss fight with Astarte, she will do a similar hearts attack that Dracula does. However, her hearts only affect male characters. Again, it's advisable for the male character to be generally weak.

SOlution by TrueAchievements
There is a secondary, much easier way to earn this achievement. The Imp enemies, found on a number of stages, have an attack where they take control of you for a brief period. Before initiating it, they will bob up and down for a bit (so you'll know when it's coming.) They will then fly very slowly towards you, and attempt to stab you in the back with their weapon. If they succeed, you will begin walking around and attacking automatically. During this time, your teammates can attack you and cause you damage. If one of them manages to kill you, the achievement will pop. This is how I earned the achievement myself, and I've done so with friends on a couple of occasions since.
