The animals cry and weep when they are being killed. Hence, meat eating should be discarded. Food conditions the nature of the mind. Mind guides the thinking. Thinking results in action.
Actions lead to commensurate or matching results and effects.
This chain of action between the food we eat and the results of our actions highlights the fact that meat eating leads to beastly actions and the concomitant evil effects. There is nothing wrong in this. It is only God that can take them and bestow His grace on you to foster good qualities. For example, suppose you have a soiled, torn and mutilated hundred rupee currency note, no one will accept it. But, if the number is intact, the Reserve Bank will accept it and give you a good note of same value in return.
