Liberation of Fish

In the movie ‘Triple Tap’,
there is a an end scene with two guys
freeing the fish they caught into the sea,
as they laugh with each other.

I hope the laughter was at their foolishness of having fished,
and that it means they will never fish again.
Is it cool and gracious to let the fish go?

Of course!
But it is more cool and gracious to not catch them for fun in the first place,
but to feed them joyfully instead!
