This depends on your own subjective view of which organizations are evil, and which aren't. WikiLeaks' biggest document dumps were about the wars in Iraq and Afghanistan, and about American diplomacy around the world. The latter also revealed countless local scandals that were big news in different countries (for example, about corruption in Tunisia, which helped spark the Arab Spring). I don't see any credible argument for the idea that WikiLeaks did more harm than good. What decisively turned American liberals against WikiLeaks was the publication of the DNC emails, which revealed a real scandal (the DNC trying to stack things against Bernie Sanders during the primaries) that had real consequences (the head of the DNC having to resign). American liberals turned against WikiLeaks for that largely partisan reason (the fact that Democrats were desperate for scapegoats after their election loss to Trump made the backlash against WikiLeaks even worse), while American conservatives wouldn't like an organization that leaks American state secrets anyways, so Wikileaks was left with no support in the US.
