Question; number one, when you say force do you mean put a gun to his head and force him, or put him in a situation where he will have to appologized based on what?
number one tends to be a short term affect, and if you are really displeased with him I would go for number two.
Also from a business perspective to many others see you using number one, you could possibly loose business after others begin avoiding you.
The funny thing is about number two is sometimes you can actually be doing them a favor. Not everyone is happy with there situation even when it comes to money. Found out an old boss after getting fired was better off, not financialy but as far as happiness goes.
Some other posts, depending on how you play out number one. You could end up with others thinking.
Forced Appologize: Your childish.
Agree that you have been wronged: You win
Any kind of Appology: Your enemy is able to admit his mistakes, which could gain him some points.
In the end I don't think he will learn much from number one.
It could also depend on a personal or business level, and what he did in the first place.
To each his own
