Capitalists aren't evil except in the minds of people who are too retarded, ignorant, or indoctrinated to understand that risking the loss of their capital by creating a business, hiring people, and paying them for the performance of labor is something that no one would do if they knew they had nothing to gain (i.e., if they wouldn't profit) by doing so.
In short, without profits there are no businesses, no jobs, no goods, and virtually nothing but poverty. It would be just like in the pre-capitalist world.
