Ulitmately, the purpose of reproduction is to pass on genetic material.  Cannabalism after mating can still prove to be a benefical behavior, because the genetic material still passes on.

Spiders like the Black Widow and the Praying Mantis are known to eat their mate after copulation.  But there are some males who fight back to ensure the continuation of their genes.
