To call someone an angel is a matter of perspective, they might be called an angel because they are kind and caring, maybe it's because they have never done anything bad before, or the person might be seen as a little innocent. Poldara is all of those things, even when he is a young adult training as a cadet in his Uncle MA's army. Unfortunately, things don't stay pure forever, and one day while training, something happened to him that opens eyes to the reality of life, and just how horrible it can get.
