The thing about virtues is there's always another side to the story.
Patience and
Temperance never take risks or do anything for themselves.
Honor can border on vengeance.
Clemence is weak and passive.
Prudence, though probably the best of the lot, is like
Patience- unimaginative and unwilling to take risks.
That said, there's enough precedence for
Pru to be unnoticed in that way- until she does something imprudent, of course- and to have a flavour of its own as a name. Together, the four names you mention call to mind the American Colonial era (and I'm not American).
