Do our good deeds outweigh our bad deeds? What if you knew someone, who did very good things, who was recognized as a diplomat, but in secret they committed heinous acts. Let's say you caught them in these acts. Would you say to that person, "Oh, you've been such a good person, I won't tell anyone the things you've done." God knows everything we do, good and bad. He judges us on the 10 commandments, just like in a courtroom.
I'm as much of a shit bag as anyone else, only difference is I've seen the way God sees sin, and I feel the same way in my mind as He does, because I've fully given my life to Him. Sometimes the only way I can communicate to people stuck in the shit pond, is to talk shit language, then I grabs um and pulls um ups, so they can see their sins as God sees their sins.
When you give your life to Christ, He will get rid of the brunt of your root rot and prune you when needed; however, this does not mean that you're completely void of sin or attacks from Satan, which means you need to fight against those sins and those attacks with repentance, prayers, patience and meditating on Jesus.
Is it possible for a Christian to achieve a sinless life, a perfect life? I guess that depends on the individual and how deep they are in relationship and meditation with Jesus. The world is full of surprises, often times not good surprises; in this we have to hold tight to and trust that the Holy Spirit will get us through rough patches, especially if we're triggered. We should strive to be perfect like God, but we will never be God. Learn more at these links and within these fun & educational video shorts.
