"Though an angel should write, still 'tis devils must print"

The quote by Thomas Moore, "Though an angel must compose, still't is devils need to print", suggests that even if something is composed with great intentions, it can still be used for negative purposes. The idea is that once something is printed or spread out worldwide, it can be misshaped or controlled by those who wish to do harm. The metaphorical angel represents the pure and great objectives behind writing, while the devil represents those who might utilize those words for their own destructive programs. It reminds us to be conscious of the possible repercussions of our words and the power they hold once they are put out into the world.
