Make this casual and informal.
Could you please explain why you transformed into a demon? Was it deliberate or against your will? Perhaps it was due to intrusive thoughts? Regardless, I am obligated to eliminate you now.

Hey, can you, like, explain why you turned into a demon? Did you do it on purpose or was it, like, out of your control? Maybe those weird thoughts had something to do with it? Anyway, I gotta take you down now, no hard feelings.
Take out the "like" parts and make slightly formal.
