Spiritual Potential and Consequences of Actions Upon reading this question, I wondered: would a person with great spiritual potential, without compassion, be more likely to cause great harm than an average person? Not intentionally, but say due to anger or hate; would this person be akin to a politician with great power who's actions can affect more? 

Thus, would spiritual potent individuals' actions have greater consequences under the effect of negative states?
Instead of "spiritual potential", you probably meant those with supernormal powers/Iddhi capability right? because those with higher spiritual potential would naturally tend to act/speak/think in a more skillful way than those who don't. If that's the case then sure. Just like that common expression "with great power comes great responsibility". A foot soldier can save or kill someone with just his weapon, but an emperor can build or annihilate an entire country with just an order! So probably a more apt expression would be: "with great power comes great kammic consequences".
