Maybe somewhat, but in the end, no. As he does agree to let, and even helps, Wendy and her brothers and even all the lost boys to leave him even though it hurts him bad and he really needed Wendy. He closes the nursery room window though in efforts to still keep Wendy but as Wendy's mothe rpleads him, he gives Wendy back. And during their adventures, when they were in a death trap, and only one of them could be saved, he sends Wendy to safety and stays behind himself. This is the point of the legendary line "To die would be an awfully big adventure." He however is saved by a neverbird, who gives her nest for him to float on - and Peter carefully places the eggs to a safe place before using the nest. So no, he is not selfish.

Tootles' action reflects the innocence and imagination of childhood, where harm is often depicted in a non-lethal way. Thus, Wendy remains unharmed, symbolizing the resilience of childhood and the protective magic of Neverland.
