The baby kept crying so I'm going to yell at it to try to make it stop.
Why would you yell at a baby?
I'm not going to be kind to it since it's not my baby, I never wanted to have a baby anyway
Just because the baby is not yours, does not mean you should not be nice. A baby needs gentle care, yelling at it is not very gentle.
Well I can't be nice then.
You should just ignore this baby because babies cry all the time. They can't help it.
