Is it bad for you to eat soap?

yes, it is bad for you to eat soap, because there are various chemicals in the soap that can cause damage to the body if taken in a large proportion. Everything is good in prportion though, so if you only eat a little bit of soap once and never do it again, you're not going to die. It's actually probably healthier than swallowing a large amount of bleach, because bleach has more chemicals for example, and if taken in a large prportion it can be harmful, especially compared to a small amount of soap.

Still, I would advise against it.

It probably doesn't taste good.
