The whole “ends justifying the means” thing.. Fair.
Well, imagine if you had worked your whole life for a goal and got within sniffing distance but couldn’t get the rest of the way because there were a few people better than you. You work extremely hard but still can’t beat them. Oh, and maybe there is $6-15 million waiting for you if you get your goal. You have no fallback plan. Your family is at or near poverty. And then I think most people can at least see the temptation to take something that helps get them over the top. It might not be right but it is pretty understandable.
