Does installing a pirated (copied) program on a work computer entail sin or expiation, especially after permanently leaving the job?

We have clarified that patent and copyright rights are protected for their owners, and that the website issues a fatwa prohibiting the copy of programs absolutely as long as their owners forbid it, even if some scholars have permitted their copying for non-commercial purposes or after the company has covered its production costs. You must repent for what you have done and delete the program if you can do so without harm.
