And the retribution for an evil act is an evil one like it, but whoever pardons and makes reconciliation - his reward is [due] from Allah . Indeed, He does not like wrongdoers. (Qur'an Ch. 42, V 40)
And if you punish [an enemy, O believers], punish with an equivalent of that with which you were harmed. But if you are patient - it is better for those who are patient. (Qur'an Ch. 16, V 126)
Tell those who believe to forgive those who hope not for the days of Allah; in order that He may requite folk what they used to earn. (Qur'an Ch. 45, V 14)
So be patient with gracious patience. (Qur'an Ch. 70, V 5)
So, based on the above verses, it is highly advisable that you forgive them.
