Best my husband and I could figure is, SE was trying to hammer in the "Oh my god look at how evil he is" line. Which, already feeling sympathetic to him, just kinda grated on my nerves more than anything. xD I feel like that was a cheap tactic.
On another note, wow I love that I woke up this morning to find such awesome discussion in my thread.
I do feel like I need to make a point clearer, however. I'm not criticizing a story for having morally grey, complex characters. What gets me is that Foulques's issues and the sympathy he stirred in me did not actually seem like they were deliberate on the part of the story. The writers seemed to be doing everything they could to drive home this idea that Foulques is bad and oh he went through lots of crap but
he's a bad guy, remember! It's the dismissive way the story addresses deep, complex issues (like the systemic racism in Gridanian society) that bothers me.
