The real problem now is not that a handful of professionals in the CIA had these tools... it's that the tools are out in the wild. Anyone could have them, or be in the process of getting them. Simply knowing the sorts of things that can successfully be done may be enough to inspire other hackers to recreate tools with the same functionality.
I think this is positive. If these weapons are out there, they will eventually also be used against government targets. As such, there won't be a desire any more by government to keep leaky hardware and software: they've lost their competitive edge that way, and are now part of the victims. So they will not hamper a cure any more.
It would be fantastic if horrible things happened to the government by their own tools in the hands of enemies. It would be fantastic if the government felt powerless in the face of their own tools. Then they will stop pushing for holes in the system (and maybe refrain from developing even more stuff that will eventually be used against them).
The NSA and the CIA have been on the wrong leg all these years (no wonder, they are government agencies). In stead of being on the defensive side, and helping the population, companies and so on, to develop secure, tight systems, they have been lobbying for holes everywhere, so that they could develop their offensive capacity. But now they are themselves full of holes, and the enemies have their weapons ; and they have equipped their citizens also with equipment full of holes, open to the attacks by their own tools in the hands of enemies. They have rendered the government, and the entire population and economy, fully vulnerable to foreign attacks, with tax money.
