Why is it impossible to not sin?

Our world is filled with sin, we are taught to lie to get out of situations, and we lie to make people feel better about themselves. One sin that is hard to stay away from is being friends with bad influences, the Bible says, “Don’t be fooled: ‘Bad friends will ruin good habits.’ Come back to your right way of thinking and stop sinning. Some of you don’t know God. I say this to shame you.” Jesus loves everyone, and I don’t think he means just don’t be friends with anyone who is a bad influence, I think He means that you can’t just let them be a bad influence on you, you need to help them or try to help them become a better person. Don’t just hate everyone just because they aren’t perfect, always give people a second chance. To avoid breaking anyone’s heart we play things safe and give in to peer pressure to be loved by the wrong people, while God and our families will always love us. It’s impossible not to sin because we are all born into it. And we play things safe too much when sometimes telling the truth would be easier, since God says it’s right, it’s always the best thing to do. It’s weird for me to think of sin and how it works, because we have a choice not to sin because we know right from wrong, but it’s also impossible not to, but we also get punished for sinning when we can’t possibly always be truthful. And I know we need to be punished for our sin or we would be horrible people. I don’t know if it’s just me but, it kind of messes with my mind to think about.
