I feel sorry for Tyler. He is literally the amalgam of two beings, one willing and one violated and he literally had two distinct personalities. Even though he was physically tyler when he killed Culber, mentally he was Voq. I don't think that Tyler can be held culpable for something that he wasn't conscious of doing. I think Saru was right in his decision to show Tyler compassion, it was a decision that i could see Picard or Janeway making.
To that end, do I think Tyler should remain on the ship? No i don't. As much as I agree with the sentiment expressed in the episode that the way tyler is treated will define who he becomes, he needs to define for himself who he is. Discovery is not the place for him to do that for a variety of reasons. My hope is that the end of the season will see Tyler being admitted to a psychiatic facility, where he can hopefully get the help he needs.
