It was less an assassination and more the beginning of a full genocide (a specifically French genocide, not against whites in general) around the country.

Dessalines went around the county killing all (fully white) French males. A lot of powerful Haitians opposed this, especially those of mixed racial background who had white family. The crimes that followed were really pushed forward by Dessalines the man, not the Haitian people in general.

Transatlantic slavery was incredibly cruel, but persecution by "the French" doesn't excuse a genocide of all French people on the island. Ironically, the people most responsible for the crimes against enslaved Africans (the "grand blanc") were largely back in France and so escaped personal harm.
