Judges 18:27-31 - They continued to use the idol

18:27,28

So the Danites took their pilfered religious artefacts and the acquired priest and went on to attack “a people at peace and secure”. Again we have this phrase “at peace and secure”, and I wonder if this is meant to imply that the Danites’ actions were merely opportunistic and not following any divine plan. They attacked and burned down the city. The people of Laish are presented as weak and defenceless. The Danites had no concern for the people there, and rebuilt the city.

18:29-31

They renamed the city “Dan”. They then set up their own idol. The Ten Commandments explicitly forbid the making of idols, and the Law (and the rest of the Bible afterwards) repeatedly warn against worshipping idols. There is reference to “until the time of captivity”, and that they continued to worship idols.  It is clear that the book of Judges does not approve of the actions of the Danites.
