With X-Men and X2, you need to consider that the director (Bryan Singer) is openly gay. I don't think he has sexual fantasies about women that are coming into play with Deathstrike's death scene.
Not everything is about sex. People enjoy elaborate death scenes in movies, regardless of gender.
The fact that some people are interpreting elaborate death scenes as being sexually motivated somewhat disturbs me.
And while defending Deathstrike, I think you're leaving out that she ruthlessly attacked other people in the movie, far prior to Wolverine assaulting her. She may have been mind-controlled, but she was a dangerous weapon none-the-less.
And X-Men isn't a stupid comic, nor a stupid movie. There is social commentary about being "different". Didn't anyone notice Iceman's "coming-out" scene?
