It sounds noble, but lets face it, he is not on a battlefield with dying comrades or something. Colleagues are not your family, they are in charge of their own

It sounds noble, but lets face it, he is not on a battlefield with dying comrades or something. Colleagues are not your family, they are in charge of their own lives and they can leave too if they want to. Would you want someone to come work a job he now hates just so that you wouldn't feel bad about him leaving? Grow up. Just start looking for a new job and leave as soon as you can. A company that makes these kinds of choices in terms of job filling cannot be worth your time.
