Wow.....what a DB
I can relate somewhat here. My "almost father-in-law" wants to dive and I truly believe he would be a good diver given the proper instruction. He has, apparently been rented gear at one point in the very recent past so that he could do some work to his dock.....I have risked all future comfort at family functions by refusing to take him diving (or even be in the water at the same time) unless he too the courses. This, I did follow up with some of the possibilities and he is now signed up to take the OW courses this month. I look forward to diving with him. You would be wise to do the same thing. As everybody has nicely (and not so nicely) said, the list of possible problems FAR outweighs the possible upsides. Take this opportunity to make the smart choice. You will both live to appreciate it.
