Thomas Aquinas states that, “It is altogether unlawful to kill oneself, for three reasons… Secondly, because every part, as such, belongs to the whole. Now every man is part of the community, and so, as such, he belongs to the community. Hence by killing himself he injures the community, as the Philosopher declares (Ethic. V, 11) (ST IIa-IIae q. 64 a.5).
How would one criticize the conclusion that “Hence by killing himself he injures the community”?
