The toughest time in anyone's life is when you have to kill a loved one just because they're the devil.

Our reading
An editorial interpretation.
The line treats killing a loved one for being the devil as though it were a familiar life difficulty. That impossible generalization produces the dark joke. The ordinary language of hardship collides with a grotesque premise, without offering a literal recommendation or a credible universal experience.
