If you don't harm someone else (I mean another human being), you're not doing wrong.
What about willfully and knowingly causing suffering to animals? Directly and unnecessarily damaging the environment?
This is a matter of opinion.
You think? So basically you have a book filled with the stories of God telling you how to live and what's a sin and what isn't, and you get to pick and choose what to follow and what not to. So, a lot of what you're doing will be disobeying God's will. So You Might as well reject the concept of organized religion altogether and just follow your own moral compass.
