Just like all religions Hinduism also maintains that eating animals outside of religious sphere, without offering it to god (s) leads to sin/bad karma, is this applicable unto kshatriyas too?
As far as i have read, eating meat without any rituals is never really recommended in any Hindu scriptures.
A Brahmana, engaged in the celebration of a religious sacrifice, becomes degraded by not taking meat.
A Kshatriya should eat the cooked flesh of a quarry after having propitiated therewith the gods and his departed manes. A Vaishya can take meat, lawfully obtained for money, after having worshipped therewith his departed manes. (56 57)
A twice-born one, by eating the cooked flesh of an animal wantonly slaughtered (not killed in any sacrifice), suffers the pangs of hell for eternal time, or as long as the sun and stars would shine in heaven.
A Brahmana, by abjuring meat, acquires the merit of a horse-sacrifice, all his desires are fructified, and he becomes an emancipated self even though he be a householder. (58)
Vyasa Smriti's Chapter 3 verses.
These verses prove that the act is not recommended for everyone from the Brahmins to the Vaishyas.
A slightly different perspective however is found in this answer.
Adding a few relevant verses from the Manu Smriti:
5.31. ’The consumption of meat (is befitting) for sacrifices,’that is declared to be a rule made by the gods; but to persist (in using it) on other (occasions) is said to be a proceeding worthy of Rakshasas.
5.32. He who eats meat, when he honours the gods and manes, commits no sin, whether he has bought it, or himself has killed (the animal), or has received it as a present from others.
5.33. A twice-born man who knows the law, must not eat meat except in conformity with the law; for if he has eaten it unlawfully, he will, unable to save himself, be eaten after death by his (victims).
The following passage from the Devi Bhagavata Purana's 1st book sums it up.
57-61. Janaka said :-- “The killing of animals in a sacrificial ceremony is not killing; it is known as Ahimsâ; for that himsâ is not from any selfish attachment; therefore when there is no such sacrifice and the animals are killed out of selfish attachment, then that is real himsâ; there is no other opinion in this. Smoke arises from a fire when fuels are placed in it; and smoke is not seen when no fuel is added. So, O Munisattama! The himsâ, as prescribed in the Vedas, is free from all blemishes, selfish attachment, etc., and therefore it is unblameable.
Devi Bhagavatam 1.18
So, for everyone the act is blameable, even for the Sudras.
God created Varnas but Varnas are decided by Karma not by birth.
Its always sin.
God created our body like a vegetarian.
I have some facts that human is vegetarian:
- Nails: All non-vegetarian have sharp nails(like: Cat, Dog, Tiger etc) but vegetarian don't have sharp nails(Human, Cow, Horse etc).
- Teeth: All non-vegetarian have sharp teeth(like: Cat, Dog, Tiger etc) but vegetarian don't have sharp teeth(Human, Cow, Horse etc).
- Drinking: All Non-vegetarian animals drink water from tongue but all vegetarian drinks water from lips.
- Digestions: All Non-vegetarian animals can digest without cooked flesh but vegetation (Human) can't digest raw flesh(without cooked).
Last and most important
- Eyes: At the time of birth all non-vegetarian have eyes closed and remain closed for 3-4 days but all vegetarian have opens their eyes instantly after birth.
