Bolaire Lathalia can be worn by someone voluntarily. Someone can wear him on purpose. He does not have to trick people into wearing him and take their lives and kill them. He can be worn by volunteers.
We know this. This is an established fact. This is how he worked up until he gained agency.
This is the context in which he kills.
In order to discuss whether or not he's a serial killer, you have to start with the fact that he deliberately chooses murder over pursuing other options, which he does have.
He can be worn by someone who chooses to wear him. He 100% knows this.
A lot of people have done a lot of murder apologia for Bolaire about how he has to do this for survival, but he doesn't. Like, flat out, he doesn't have to kill to continue to exist. He could choose to work with people and find compatible partners who are willing.
He doesn't.
