Yes, nuclear energy is good enough to balance out the harm, because it creates a great deal of energy with very little waste. The waste produced to make nuclear energy is very little compared to the waste associated with making coal power. Nuclear waste is for the most part safe, and provides a great deal of energy without dependency on other countries.
Nuclear energy is a victim of the same kind of negative press of certain airlines used to be - jut like air planes crash rarely, but are very high profile tragedies, so too are problems with nuclear plants. There are far more nuclear plants in the US than people believe, and their accident instances are low.
Nuclear energy is good enough to balance out the harm. Nuclear energy is cleaner initially than coal or other types of fossil fuels. The risks can be dealt with in advance, and proper precautions can be taken in respect to waste storage and meltdowns so that they do not happen.
A lot of harm was caused when the atomic bomb was released and the threat of this is always with us. The damage is too great to justify the benefits. What we needed to do was to find out how to utilize other, alternative forms of energy instead of this.
Nuclear energy is not good enough to balance out the harm. Nuclear energy is bad for the environment and is very costly. It also contaminates local water supplies and there is no safe way to mine the materials needed to produce nuclear energy. Exposure to the radioactive materials can be deadly. We already have other cleaner methods that can be used instead.
