Haki is not inherited as far as we know.Rayleigh and Ace sure have it but i don't remember anywhere in the anime being mentioned that Roger had haoushoku or any other kind of haki of that matter.Please provide specific proof, but even if you do, since i am sure it's not mentioned in the manga, which is the only cannon referance for One Piece, it's not true.Fact, end of story.Personaly, i believe he had it but still it is not yet confirmed so we can't take it for granted.

"I'm not gonna die partner".Obviously a metaphorical phrase.Roger knew that by doing what he did just before he died he would inspire people to follow his lead to freedom and adventure and among them there would be those who could find one piece and carry on his will by doing what he didn't have the time to do.
