Retaliation would likely go way up, and I suspect this woman won't be unharmed for too long post his recovery.

This is one of those situations where you have severely harmed someone's QoL and I feel to the point where the consequences of retaliation are lower than the drive to perform it.

Can't say her action wasn't warranted but... on both sides actions have consequences and the likelihood he won't retaliate is low (especially if he can easily reach her).
