Lying is bad because a generally truthful world is a good thing: lying diminishes trust between human beings: if people generally didn't tell the truth, life would become very difficult, as nobody could be trusted and nothing you heard or read could be trusted - you would have to find everything out for yourself.
1. you're avoiding facing the truth and you're not progressing or growing as a person. 2. Losing people’s trust. 3.Shattered relationships. 4. A bad reputation. 5. Losing your identity. Hope this helped have a nice day!
