Tools which are not invented cannot be used for good, there is some logic behind that. It is necessary but not sufficient for good. There is also fundamentally a tension between freedom and good. Since being free to use technology also includes being able to use it for evil. Not to mention the track record of trying to enforce "goodness" has been less than promising historically.

And that is before the inherent fundamentals of dual use. There is nothing we could do to keep fire from being fundamentally capable both of keeping someone alive by preventing freezing to death, and sterilization and is usable as a self-replicating weapon of destruction. Basically you can only control how well our surroundings handle being set on fire, not make arson an impossibility.
