Categorical imperatives are universal and unconditional.
The categorical imperative is a concept created by the brilliant German philosopher Emanuel Kant in 1785. The concept appeared for the first time in his work called "Groundwork of the Metaphysic of Moral," as part of his ethics and moral studies.

For instance, the categorical imperative "do not kill." For Kant, it is universal, unconditional, as part of the moral of humans.
