[Star Wars] If Sith can gain strength from pain, anger, rage, etc, is it be a viable strategy to be earnestly kind to them during a fight?

If you were a Jedi dueling a Sith, could you continuously pay them compliments, offer kind words, smiles, etc in order to lower their strength? I imagine it would be mildly confusing or annoying, but would it actually help to combat the power they get from the dark side?

For example, Kylo Ren intentionally put himself in pain by irritating his injury in the Force Awakens in order to pump himself up. If Rey had sweetly offered to heal him or told him he's a good boy would it have had the opposite effect?

If someone is so warped and twisted by rage and self-centered logic that they're lashing out with brutal lightsaber attacks, they're very unlikely to listen to any kind words. Or they could (correctly) assume it to be a tactic meant to weaken their resolve, which would only anger them further. 

It's like trying to reason with someone on a cornucopia of different mind-altering drugs. It very rarely works, and often gets misinterpreted into something far worse than you intend it to be. 

Using Kylo Ren again, this was exactly what Han Solo tried to do in his last moments. While it wasn't exactly a fight, it was still a struggle between Ben's dwindling true nature and the darkness he chose to embrace. All Solo did was help reinforce Kylo's decision and set him deeper down the path of the dark side.

Similarly, when Padme tried to earnestly calm Anakin down on Mustafar and begged him to let go of his rage, he responded by choking her.
