Thou Shalt Not Kill is the most serious crime among people and anyone who takes a human life should be punished. Samson on the other hand killed many of people who were trying to make slaves out of his own people but Samson did it in self defense.
But God put his second Commandment above Thou Shalt Not Kill. Some don't comprehend that God is a Jealous God and does not approve of bowing down to any graven images or even glorifying any of them.
