Putting your murderhobo retardation aside for a second, even if you didn't kill the scavenger brood NPCs and Moore you'd still be locked out of some items related to the key one you missed, because there's a mutually exclusive choice for the Dragon Communion Priestess where you either get a hammer or her summon.
Similarly, Hornsent also has a mutually exclusive choice between a talisman and an ash of war so you have to replay through the DLC at least one more time to get the other mutually exclusive quest rewards you're going to inevitably miss.
In short, even if you did go full retard you didn't actually fuck up anything major so stop bitching.
