I really don't think Clark is that devious. He's just doing his best to help out his friends. He's maybe a little naive, and he does seem concerned for their relationship.
But Lois and Chad are not Clark and Rachel -- I mean, their situations are different. Lois and Chad are married, they have a much stronger, more binding commitment than Clark and Rachel did.
As for Chad, I agree that the girl with cancer story was not very realistic, but it was just an illustration of the types of things that bother him in a "treat 'em and street 'em" operation. I don't think Chad is a bad guy at all.
And I actually know people -- well, my brother and sister-in-law -- who burned out on that kind of medicine, and joined the Indian Health Service. Now they live on a Reservation in Oregon, and practice real live family medicine, anything and everything. They've never been happier. And it's not just a honeymoon high; they've been IHS for something like 9 or 10 years by now.
Anyway, I think this is an interesting set of conflicting priorities you've set up here, and I look forward to seeing how they get resolved.
