it fits the pattern for either one or both being homosexual.
There's no evidence that either one is a sodomite. One was drinking and the drink may simply have compromised any sound judgment he may have had.
Drink first compromises judgment. And after considerable drinking only then it will effect ability. He apparently was not compromised enough to not be able beat the other marine to death. But he was compromised judgmentally enough to jump from the 3rd floor.
