Question

is it bad?

Answer 1

no, just bruising  

Answer 2

No, it's not necessarily bad for you. it's just bruised and sometimes sunburned. It's not going to kill you if you eat it...as if you've never eaten one before! I love bananas and i've never had a problem with the black stuff because i know that it tastes about the same just a little bit more soggy than the original banana insides...!

Answer 3

Just overripe.  You can just cut it away, eat the rest, it won't hurt you.
