He betrayed you. A crime against humanity and ultimately to himself.
The evil will grieve in the thought realm .Even after the physical body decays .They will mourn for their evil deeds.
Do not rejoice in this fact .Or recognize your own mental superiority to not bare this consequence. This curse after life .Rejoice in your innocence .Rejoice for your defence against desire .Rejoice in your visualisation of innocence and strength and perseverance .
He is a weak tree ruled by Mara (desire).
