just finished watching ALIEN

now that I am older and I understand things more

I've come to the conclusion the ALIEN just wanted some Sugar

he killed all the males on the Nostromo because he is not Gay so he had no use for them

he killed Lambert, the other Female because she was skinny and ugly and whiney and weak;

after all, all males want a strong female as the Mother of their offsprings and Sigourney was the strongest one
