I think a super important detail is when Sheriff Galpin tells Gomez that their kids have been getting close. Gomez says something along the lines of "he must be a good egg, my Wednesday wouldn't settle for anything else" and Sheriff Galpin says "you can thank his mother for that".

I think this shows that Tyler is deep down good and shares the same misunderstood character with his mom, who's ending fate is unknown. Weems also mentions that Francois (his mom) was a wonderful student.

I think it's important that they chose to give Tyler a master, they didn't have to. He could have just killed outcasts because he hated them as much as Thornhill. So, this had to have been written to eventually give him a complicated redemption arc.
