This is literally how Haiti was started! And look how well it went since then!

On 1 January 1804, Dessalines proclaimed Haiti an independent nation.[17] Dessalines later gave the order to all cities on Haiti that all white men should be put to death.[14] The weapons used should be silent weapons such as knives and bayonets rather than gunfire, so that the killing could be done more quietly, and avoid warning intended victims by the sound of gunfire and thereby giving them the opportunity to escape.[18]

Girard wrote that since black generals took the property belonging to the white ex-slaveholders, "economic interest" prompted the massacres.
