this is something a lot of people dont get . its your ambition that is relevant here , your willpower is not really the thing in question . boromir had fuckloads of willpower , yet fell to the ring rather quickly since he had so much ambition . faramir , while not being as full of willpower as boromir , managed to not only resist the ring but also to acutally to decline it and give it away , a feat very few people have done . galactus is more powerful than sauron , the ring would mean nothing to him and have no effect on him . When people say no man can resist the ring , its the man part in there thats important . it implies mortal . unless you are more powerful than sauron and can just overpower the ring , if you are mortal and have ambitions , it will excert its corrupting influence on you .
