A thing may be morally neutral and yet the desire for that thing may be dangerous. As Byron has said:
Sweet is a legacy, and passing sweet
The unexpected death of some old lady.
The painless death of a pious relative at an advanced age is not an evil. But an earnest desire for her death on the part of her heirs is not reckoned a proper feeling, and the law frowns on even the gentlest attempts to expedite her departure.” —C.S. Lewis, “The Inner Ring”
