Evil isn't the right word - it implies that the church is full of evil people which isn't the case. It's the rigid doctrine combined with the political power and influence which is the problem.
A bit like calling Margaret Thatcher or George Bush or Tony Blair evil - I don't think they are evil people, but they are/were people with a lot of power who put in place policies which some people say caused harm and were therefore 'not good'. That is not to say that they never put into any 'good' policies though.
But at least they were elected, and could be removed from power when they became too unpopular.
I have no idea whether the new Pope is a genuinely 'nice' person or not, but if I were in charge of PR at the Vatican I'd certainly be putting someone like him out there.
