There's a passage I got memorized, seems appropriate for this situation:

Ezekiel 25:17.

"The path of the righteous man
is beset on all sides
by the inequities of the selfish
and the tyranny of evil men.

Blessed is he who,
in the name of charity and good will,
shepherds the weak through the valley of darkness,
for he is truly his brother's keeper
and the finder of lost children.

And I will strike down upon thee
with great vengeance and furious anger
those who attempt to poison and destroy my brothers.
And you will know my name is the Lord
when I lay my vengeance upon you."

Quentin Tarantino - 1994
