Dessalines was L'Ouverture's principle lieutenant and general. It wasn't until after the Battle of Crete-a-Pierrot, where Dessalines forces kicked the french out of fort Crete-a-Pierrot, then massacred the french civilians, and then themselves were forced out of the fort due to heavy losses on Leclerc's counterattack, that Dessalines switched alliegences. Dessalines than switched sides which led to the surrender of L'Ouverture. The massacre of french civilians there still happened under L'Ouverture. He didn't have a different ideology, he was literally L'Ouverture's primary supporter and ally, until defeated militarily.
