Why do people view the world with a gray mindset? Because it keeps us sober about human nature. You can support someone, but don't believe in them unconditionally; you can love, but don't give yourself completely, and don't get too emotionally involved. Because when they make mistakes, the trust and love you once gave can often turn into anger. It may not necessarily be their fault, but an inevitable aspect of human nature—more precisely, it's because you set your expectations too high.
