The very fact that this instantly feels like ironic jest illustrates how impossible it is to seriously limit licenses with broad moral clauses.
One could come up with clauses that could be admissible at court, e.g. "this software is expressly not licensed to be used for anything intended to kill humans". It would not be licensed for military planning software, but would likely be still licensed for a military transport system, or even an anti-drone weapon.
The best actionable clause I could come up with is like so: "your license to use this software for any purpose terminates as soon as a court of [insert jurisdiction] finds that it has been used for [something you are opposed to, but also sufficiently clearly defined, like genocide, or incarceration of peaceful political dissidents], which has resulted from the use of your products and services, and with your prior knowledge of such use". I think I've even saw similar clauses in many commercial licenses, just with not morals-related provisions.
