He literally interfered in the war on the Fae's behalf, leading to an uncountable number of deaths for the youkai. While Wilhelm said some....mean words? I think your perception of assholery is a bit skewed :V.

What part of this is racist? It's about him blurting out the question. Ron in the early days lacked a lot of common courtesy.

You realize, that at the end of the day, they're all killers right? Even Jeanne, the literal Saintess had presumedly killed a lot of people while fighting in her war. Fighting, death, killing, it's a very static point in their lives. They entrusted her with a ridiculous amount of weapons and things that could do a great deal of harm. They were just reminding her to not just kill unless it literally comes down to her or someone else, thereabouts. Not to mention she's going to a school where every student is armed with a weapon capable of killing. This isn't an instance of her simply going to a random school and they're like 'alright Kunou, don't stab anyone in the eye with a pencil'. My dad gave me a similiar 'talk' when I was younger when he taught me how to shoot a gun. He specifically pointed out, that I never point my gun at someone I'm not intending to kill, but if it comes down to it and it's me vs the other person and I'm in danger, I should pull the trigger without hesitation. Same logic is applied here.

No, Odin agreed if Wilhelm didn't fight him, he said nothing about fighting Lacelot or Guinevere.

No, he said he would fight if Godou interfered because he wanted to analyze Wilhelm.

He's stopping Godou from interfering, his whole purpose was to see Wilhelm go at it and figure out what's going on there.
