As someone who is building a VC firm with a focus on social impact I can say unequivocally that this can be done. You can be focused on doing good while also being a capitalist. It's not a binary. If an investor is interested in only making lots of money, there are plenty of funds that do that. However, there are a tremendous amount of investors who are happy getting a lower return on their investment if it means they can contribute into something that is making a difference. I don't see how this is any different.
