Compared to other religions, I understand that take, if we neglect stuff like not living up to their own doctrine of, e.g., equal rights between women and men, or the Khalistan movement, which has caused death and abused human rights on several occasions, also by killing civilians.

Still, as most organized religions, it became emergent as a tool of mass control and subjugation. Moral behaviour is not formed by critical thought and self-reflection, but by devotion to some mysterious higher power. Which is and always has been a core issue of problematic behaviour we can so often observe today with religious people. A side-effect is that it has the danger of hindering progress and societal evolution by having a creationism as one of it's core teachings, as far as I know.

A further form of subjugation, hindering freedom of individual human (and harmless) expression, can be found among the Kakkars. For example the "dress-code" with having uncut hair, cotton undergarments etc..

I could go on. So to make it short, no, religions are usually detrimental for the long term constructive development of humanity and Sikhism is no exception.
