The concept of going to "hell" is a religious belief held by some faith traditions, and it varies depending on the religion and its specific teachings. In many religious traditions, marriage is considered a sacred institution, and it is encouraged for various reasons, such as procreation, companionship, and spiritual growth.
However, not getting married does not necessarily mean someone will go to hell. Most religions teach that one's actions, beliefs, and how they live their life, including factors like kindness, compassion, honesty, and morality, play a more significant role in determining one's spiritual destiny.
Ultimately, beliefs about heaven, hell, and the afterlife are matters of faith and vary among different religious traditions. If you have concerns or questions about your religious beliefs, it may be helpful to seek guidance from a trusted religious leader or study the teachings of your faith for a better understanding.
