In general I believe that there are no hard and fast rules about the expression of feelings in life. I agree that going on about all the emotional agony you went through to make the decision is worse than useless, but expressions of remorse like "I'm sorry it didn't work out" are totally fine in my opinion. A statement like "It's not personal, we had to make a business decision, and it wasn't easy." also communicates that the employee is not totally expendable, if that happens to be true, while also communicating personal concern.
