I'm afraid you won't be able to enter the Five Sounds Sect and help them with their Sect Tribulation. Also, if you didn't fight for them back then, those two treasures, Silver Light Wings and Orange Light Wings, wouldn't be yours.
Moreover, when you killed others back then, it also showed the dominance of the Hundred Peaks Sect. Because you gained fame in the Eastern Province, when those people from the Demon Sects of the Eastern Province attacked us in the Eastern Wasteland, upon learning you were the Sect Leader of the Hundred Peaks Sect, and realizing our strength, they retreated.
Had you shown constant restraint then, everyone would have thought the Hundred Peaks Sect was weak. Perhaps at that time, the Soul Breaking Demonic Sect wouldn't have come to cause trouble, but many others from the Demonic Sects would come to plague us."
