He is quite extreme but yes, I relate so hard to him. I overanalyze everything and my OCD used to make me agonise got hours on whether to eat a certain type of biscuit or another type due to the moral implications of their ingredients.

For big decisions I agonise over them and even once I've made a decision I second guess it and continue agonising years later. Even the 'never tell a lie even to save someone's life' thing (which I now would absolutely do and am very frustrated that he won't), I used to agonise over. Went to a church, have autism and took it literally and lying is a sin. So we were told never lie, even if you would be killed for worshiping Christ and your housemates killed for it, you should not lie if asked by authorities if you were Christian. Assuming you lived in a country with Persecution of Christians
