If you must kill your mice, at least dont torture them.

Catching them live and putting them outside costs nothing.

They're house mice, SFAIK they don't live outside. They'll just head
for the nearest house, to resume their function of leaving a trail of
urine and droppings across every surface where food has been handled.
Or they'll be intercepted by a cat on the way.

There's no bunny hugger route to dealing with them, releasing them
just passes your problem, and the problems caused by the myriad
offspring produced in their short lives, on to many other. Bite the
bullet and just kill them.
