This whole story of Micah and the Danites illustrates the terrible spiritual apostasy that corrupted Israel during the age of the judges. Even the grandson (or descendant) of Moses took leadership in it. It was no wonder that Israel had trouble with her external enemies (chs. 3-16) since she was so spiritually corrupt internally (chs. 17-18).
