Should not fully follow other people suggestion

First time I played Drakengard 2, I was still in primary school and I consider this story is very bad and make me confuse but only fun in gameplay...Recently, I concern about this game, and discover that I was wrong, the story actually is awesome than I thought...

The story is about : Drakengard’s world created by God, God has given human a woman named goddess, the goddess will heritage once she death naturally. But once the goddess death unnaturally, that God sent his angel would destroy the world, therefore human set up a joint military to protect goddess.  Main character is the teenager who raising by a black dragon.

What important plot give me a lesson?
The main character in Drakengard2 , Nowe as a knight, should protect the seal which limit the action of red dragon who become goddess in drakengard 2. It is to protect the dragon from unnatural dead, or else the world will be destroy........ Lol, red dragon become goddess. But Nowe choose to destroy the seal to free the red dragon because it sacrifice many unrelated people to give the power to the seal.(Seal need many resource) But it is to late, after the seal have been destroyed, the red dragon become MAD and cannot think normally, then destroy everythings due to she been sealed for a long time. (Sorry for spoiling!)

What i learn about from Drakengard 2?
After played this game, I learn that a person should not always follow other people suggestion, we should try to create and find our way in future. Or else, we just keep turning in a circle and keep repeat the same things and mistake. Same as well, we also cannot to force other people to follow our opinion because the things suit to our self are no necessary suit with other people.

How to find real answer?
Although there are many problem and Nowe feel regret and worry about the things he do is correct or no, but Nowe will growth up after facing those problem and find his own correct answer. This is a good lesson. We suppose to press on our selection although other people said this is no a good idea or wrong.Can listen other people suggestion as refer. In the process, may be have a lot people will think I am a stupid or a foolish person and say the things I do is wrong. But people should believe ourself and the decision we made.  Those are obstacle to us to get the correct answer! The more the obstacle we across, result in more confidence to the answer we get in the end.

Did I always repeating the same mistake?Yeah, I always cannot make my own decision!I always follow other people 's answer and suggestion. 
Find our own answer, that is! A answer which we think is correct!
