Perhaps it is their 'dehabilitating handicaps' - as you call them - that empower their good scientific work, ippy. That would certainly seem to be the case amongst many religious people who do a variety of work from care work to financial management, 'science' to social work, etc.
And why then are their motivations any different to all those non religious scientists working away diligently to true to understand the world better and to try to find solutions to the world's problems.
Why is their motivation different to the countless number of non religious people doing a variety of work from 'care work to financial management, 'science' to social work, etc.'
You seem to be implying somehow that religious people are the only ones, or even more likely, to be engaged in activities that benefit society. That is not true.
