It sounds as if you don't want an answer to your question but I'll give you one anyway.

It's a question of will.

While he was the Kanima, Jackson's will was not his own. He could not form the motive necessary to be held guilty for his actions.

The physical act of killing, however, is all that is necessary for the change in eye color. This is regardless of motive.

For example, Derek killed Paige out of love not malice but his eyes still turned blue.

The Kanima was Jackson's body not Jackson's brain.

He's not guilty by any human measure - but his body still did the killing.
