It's not that we become sinners only when we commit sins; rather, our innate sinful nature drives us to sin. Therefore, everyone is a sinner. We all have sinful nature such as selfishness, pride, envy, greed, and anger, which drives us to commit various sins. The sinful nature is deeply hidden in our thoughts. Without learning wisdom and repenting, we cannot enter the kingdom of God.

Satan used to be an angel as well, and he was also spiritual. However, he fell from grace due to jealousy. Satan has been lost and fallen for a long time, and his wickedness runs deep, making it difficult for him to free himself. Nevertheless, God won't abandon him forever, even if it takes millions of years. God is merciful, just, and almighty.
