It is a private matter. When we put people into positions of trust, we want to satisfy ourselves that they are trustworthy. I am not saying we should judge others harshly. Obviously, there are degrees of impropriety. Again, we should be careful.
Persons married to adulterers are victims, and deserve our sympathy.
At some point, however, you have to stop being an enabler. Hillary has not reached this point. Therefore, we should defer to her decision about what to do with Bill, whether to again accept him back, or to divorce him. Having said this, her decision on this matter has nothing to do with our judgment of his suitability to hold a position of trust. It was not sexual harassment.
