other way I guess. everyone's born in a way- they get to choose which they want to be. bad, good, or whatever. it's what they choose

naturally bad and have to work to be good

I think that your first action determines whether you are 'bad' or 'good' at the beginning of life. Humans are actually built to lie. But that depends on how you look at it. Lying can hurt someone, but in a way it can also help someone. I guess you are influenced by what is around you, and go on with life with that foundation. Whether it's considered good or bad, people work to be better.

I am a Christian and I believe that all humans are born into bad habits (aka sin). The only thing that can bring us out of this sin is Jesus' sacrifice and love for us.

that completely depends on what ones morals are. first you must ask "what IS good? what IS bad? what is the difference? and do they even exist?"

This is basically asking the classic 'Is evil born or made?'
