Karma: Freedom from Reactions

                                                                  Q. 1. What do the scriptures including the Bhagavad-Gita and Srimad Bhagavatam have to say about "collective karma"? Our individual karma is generated by our own intentional and unintentional actions but what about the actions we perform as part of a group or as a society? Does responsibility get assigned to each one of us? Particularly, in the context of the planetary environment, we have collectively made impacts on the earth and are now seeing the consequences.

                                                                  Q. Please help me understand the term 'sarva papebhyo mokshayishyami' (BG 18.66).

                                                                  My understanding is that a conditioned living entity accrues sins and material piety when not engaged in devotional service. When Krishna says He or His bonafide representative delivers from sinful reactions, what happens to the material piety accrued? Does sinful reaction include both sins and material piety? Wouldn't the living entity be still entangled due to material piety and thus not relieved from material bondage? Or does Krishna take away both sins and material piety when a living entity surrenders unto Him?

                                                                  Q: My father is now deceased, but was a diagnosed paranoid schizophrenic. He was placed in a mental hospital for years.  My brother is also paranoid schizophrenic and is on strong medication.  I grew up observing the actions of the mentally ill.
                                                                   
                                                                  As such I look very carefully at the reasoning given.  I am a retired police officer and have come in contact with many people who are mentally ill.
                                                                   
                                                                  Now to the question, If a mentally ill person believes his delusion and acts according to it (harming or killing), does the mentally ill person acquire karma? 
                                                                   

                                                                  Q: Srila Prabhupada writes in his purport to BG 18.47, “Similarly, if a ksatriya engaged in his own occupation kills an enemy, there is no sin incurred.”

                                                                  But then in the Mucukunda story, a little different slant is given in the Krsna book:

                                                                  Q. Part 1: Krishna says in BG "Surrender unto me and I'll take all your sins" but sometimes we see a devotee of Krishna also suffers. So please explain how karma affects a devotee (i.e. karma done in previous life, in this life and all future karmas).

                                                                  Complete surrender to Krishna destroys all stages of karma, both a priori and a posteriori, just as Krishna promises. In other words, a fully surrendered devotee is NOT AFFECTED by karma.
