Therefore, Anger is not so serious sin. I think Lust is the second serious sin. Envy exists in one's world, because I think Envy is the most serious sin. If I murdered someone it is caused by Envy. I think lust is the most serious sin because lust connects crime or murder.
People commit violation, because lust is too big.
Other six sin seldom connect murder. Everybody has lust. If you have strong lust, you may be criminal. And lust arise envy, anger and so on. I think sloth is the most serious sin because a human has hands and foots and body and a intelligence for work.
