And you also forget, among the founding principles, "life, liberty, and the pursuit of happiness" rank equally. To enslave a fellow human being is as bad as killing him. If Taney's law is to be believed, killing him was of no consequence in any case - the slave had no rights worth respecting.
Sin attends sin, and where there is sin, further sin follows because sin is corrupting. The sins themselves are still individual though, thus the effect of murder does and will always constitute a more grievous deprivation than that of slavery.

Incorrect. While they are equal as sins, they are not equal in effect. Slavery deprives liberty while murder deprives life. Liberty may be exerted to some degree even under deprivation, and may always be regained. Life, once taken, cannot be regained. Thus murder's effect is ultimate in nature while slavery's is not.
