Allen wasn't a kind person, but he also wasn't an evil one. He was more in the gray area, and he preferred it that way. After all, nothing mattered except for his lover, Iris Aria, and his siblings, Asther and Alisceon. Allen also didn't forget about his sworn brother, Seref Zenchi.
As for his chat group members, he thought of them as his comrades. But he wouldn't risk his life just to save them if they were ever in trouble in comparison to his loved ones being in danger.
With that thought in his mind, Allen waited for Distere to respond to his question. He had already given Distere a clue that he was on his side due to being a follower of Lord Zenchi, which, technically, wasn't a lie.
After all, there was also Zenchianism in Allen's world and he had long discarded his identity as an atheist and became a believer in Zenchianism after he found out that the chat group that granted him his supreme talent was created by Lord Zenchi.
