The mold on bread is not very tasty but the mold on bread is not all that dangerous and it's safe for your health if you did eat a bit of the mold on the bread.
However you don't want to purposely eat the moldy bread but accidentally eating some moldy bread is not gonna kill you or make you sick enough to lead to death.
You might get an upset stomach, diarrhea and possible vomiting depending on how well your stomach takes the mold.
I've eaten moldy bread accidentally before and I just got an upset stomach which went away within a few hours.
The mold won't taste very good so you'll not want to eat enough of the mold to make you sick but the mold on the bread is not dangerous to your health.
You can take off the moldy part of the bread and eat the rest of the bread and it will be perfectly okay to eat.
