Are you in a quandary about hiring him simply because he's from Ukraine? If he's an ethnic Ukrainian, you'll have one type of conversation. If he's an ethnic Russian, you'll have another. Maybe you think he might be too highly emotional, distraught, or depressed to give a quality massage?
Or do you suspect that his business is down because clients are avoiding any possible connection with the war? Then you should definitely hire him!
I think there's no real quandary here. Maybe just a decision yes or no?
