Well you say for personal gratification. Does that include fulfillment of a contract? Because yes indeed, we can impose our will on someone to follow the laws of society and to uphold a contract they've made with us - would you consider that "personal gratification"? And it's moral and proper that we do so.
But it sounds like you are trying to frame your question into saying is it ok to bully others. And you're calling people who don't answer the way you would like stupid. So I'm not sure what your agenda is here, but it doesn't seem like such an innocent question.
Not in my book it isn't. That's a double negative. To impose upon an innocent human being, cannot be justified by anyone other than the one who is innocent. Mankind has authority over all life on earth, except his/her own. Hope you understand what I mean.
Anything with the words impose and personal gratification in the same sentence probably isn't morally justified. The way I see it is that it's only morally justified if you aren't directly harming somebody or intentionally indirectly harming somebody. Morals can be tricky, though. I'm sure there are scenarios that could prove me wrong, but imposing your will on somebody whether it was better for them or not is wrong to me, I think. It's best not to interfere with somebody else's will unless theirs does with another's. That's where morals get tricky. In that case I would try to choose which side was more morally justified. If they're not imposing anybody else's will then I'd leave them be.
