If suicide be supposed a crime, it is only cowardice can impel us
to it. If it be no crime, both prudence and courage should
engage us to rid ourselves at once of existence when it becomes a
burden. It is the only way that we can then be useful to
society, by setting an example which, if imitated, would preserve
every one his chance for happiness in life, and would effectually
free him from all danger or misery.
— David Hume
