Luke is the type that needs to believe that their is some type of "spiritual ultimatum," that we are not just pieces of organic material clinging onto a giant orb flying off into space. Worrying about who and what I stroke off too helps alleviate those anxieties and brings to focus better his wish to belong to something greater then himself, in this process, it helps confirm his hopes and add to his "mental masturbation" of spiritual superiority.

Luke, we both jerk off to sick things, yours is just a little more twisted.
