Right, hypothetical situation, say you are walking minding your own business then you see a burning car wreck, and the people inside are ostensibly meat eaters- won't you, by saving the people inside, in return have caused the deaths of the hundreds/thousands of cows/chickens/fish that they would consume throughout their remaining lifetime? Or lets take this a step further and exaggerate the situation even more, say the people inside are serial killers/nazis/israili war criminals/ jihad extreemists/child molesters/etc - should one follow the general "value all life" rule or should one indeed look at the laws of causality and how rescuing them might bring some good karma to you in the short term but in the long term by rescuing them you might indeed recieve some very bad karma?
