Why does Menelaus still value and accept Helen, even though her elopement with Paris led to the Trojan War?

Menelaus still values and accepts Helen because she is still very beautiful, he also blames the gods for her actions and not her.

Explanation:

Helen is the most beautiful woman in the world and that was why Paris wanted her.

Although Helen went with Paris willingly, the legend tells us that it was at the will of Aphrodite, who promised Paris the love of the most beautiful woman in the world in exchange for a golden apple. (The apple itself wasn't really important as it was a contest between Aphrodite, Hera, and Athena to see who was the most beautiful goddess.) So, invariably the decision to go with Paris was not Helen's fault but the blame rests with the gods who made her do it.
