This is not actually a moral choice. A moral choice has to be a choice between two evils. If it is a question of choosing right from wrong, there is no choice as one would have to choose 'right'. Therefore, a moral choice would have to be a choice between two evils and eating meat is not a moral choice.

If you think eating meat is morally wrong then you should not do so. If you don't believe eating meat is wrong, then it is not a moral choice, merely a lifestyle choice.

Victory attained by violence is tantamount to a defeat, for it is momentary. Mahatma Gandhi
