Luciel began asking questions about bases because he wanted Dan and thers to go to the north base.
He could see that they were still good people, and even if they had bad intentions later, he could deal with them properly.
He just wanted to invite them to the north base to act as temporary helpers.
So, even if they weren't purely good, then it would still be okay.
They will surely meet a lot of zombies later, so it's good to have more helpers so that they could also deal with the zombies around.
Luciel doesn't want to work that hard, so it's good to have Dan and the others.
If he and the kids are the only ones traveling north, then he would have more work to do.
He always had to watch them when fighting zombies. He also had to deal with a lot of zombies that the kids couldn't handle.
He also needed to drive because the kids couldn't drive yet. Even if he taught some of them to drive, they could only drive on smoother roads.
