One thing we can be sure of is that if sin had not
come into the world there would have been no
sickness, blindness, or death.

God said that everything that He created was
good.

Therefore, mercy has come about because of sin.
It could be a parents or it could be the result of a
sin committed by someone further back. Or it
can be the result of the individual themself.

Sin always opens the door for the devil to do his
work in people's lives.
