What can happen if you digest a living cockroach?

Answer 1

Probably nothing. It may depend on where the roach has been. For example if the roach lives in conditions that do not harbor germs harmful to humans you have nothing to be concerned about. However if the roach you ate lives in conditions that are unhygienic you may catch something from it. people eat insect all over the world deliberately without it doing them any harm.

Answer 2

After the first two cockroaches (deliberately) consumed, you will not suffer from any side-effects short of your body's reaction to whatever bacteria the devoured animals have collected on their low-flung carapaces.

However, after the third (3rd) cockroach is (deliberately) consumed, your eternal soul will be consigned to the nether realms. Depending on any arrangements between the (deliberate) consumer and the Lord of Darkness, you will slowly awaken to increasing diabolical powers, alongside an increasing willingness for varying degrees of mischief, even evil. In due time, your will shall be forfeit, as you will be another instrument of darkness, with little to no traces of your former identity. If no arrangements are undertaken between the (deliberate) consumer and the Prince of Lies, you will benefit from none of the advantages of diabolical powers, but shall nonetheless be consumed yourself by darkness.

Answer 3

If a cockroach made it into your stomach while still alive, I don't think it would make it much past that as the acid in your stomach, which consists mostly of hydrochloric acid, is incredibly strong.
