This fandom is so obsessed with angry Remus as if Remus John Lupin was even capable of being angry or holding a grudge. This man had an inferiority complex the size of the fucking moon. He internalized society's perception of werewolves and he loathes himself for being one. He didn't believe he deserved to be angry, and he proves it in canon over and over.

When Snape outed him as a werewolf and he resigned from his post at Hogwarts, he agreed that he wasn't fit to teach with his condition and graciously packed his things. Later, he said he held no resentment and even expressed gratitude for the fact that Snape brewed Wolfsbane for him and had the decency to never tamper with it despite their rough history.

When The Prank happened, he was very quick to forgive Sirius (assuming he even felt the need to forgive him in the first place) because they're chilling by the lake weeks later and he's asking Sirius to test him for their upcoming exam. Honestly, I'm of the mind that there was no fallout after the Prank because Remus would have just brushed it off and pretended it was no big deal (even if deep down he was genuinely hurt by it)

And I'm convinced that he didn't even resent Fenrir Greyback for seeking him out to bite him. He never once expresses a desire for vengeance, and even admitted that he felt pity for the werewolf that bit him until he learned his identity.

When he caught himself sounding ungrateful while talking to Harry about being forced to live among the pack to spy again in HBP, he immediately corrected himself and said, “I am not complaining; it is necessary work and who can do it better than I?" (Also a nod to Remus' hero worship of Dumbledore and his desperate desire to serve his every whim) ((seriously, dominant Remus WHO?))
