It will be interesting to see how this bias is maintained in The Mandalorian Season 2 following the development of his relationship with IG-11 and watching the bounty hunter destroy itself so that Din, Greef Karga (Carl Weathers), Cara Dune (Gina Carano), and The Child could get away from Imperial forces.
Throughout The Mandalorian Season 1, the character doesn’t make any effort to hide his prejudice against the anthropomorphized machines, and you don’t have to be Sigmund Freud to understand that it’s probably because droids murdered his parents.
As a general rule, people who experienced the death of their parents at a young age typically don’t love to be reminded of the trauma, and that very much explains the relationship between Din Djarin and droids.
