The thing that Mel Gibson, as a character, gains from the complexity of the War is that he gains knowledge on war, tactics, and honor. He gain honor in joining the army to fight the British. Also he learns and gain knowledge about his children. How they are responsible and learn very fast. He also gains knowledge on that for every gain there is a cost.
The cost that Mel Gibson, as a character, pays is the lose of his to sons, Gabriel and Thomas. This was a sad and pitiful moment. Also he lost some of his friends, family members, and his home. Not just his own but also others. Even though he paid a large price, he gains something that is in some people’s perspective worth it.
In my perspective, I think that the gain and lose outweigh each other. They weigh the same. A large cost for a large gain. In other words, death of beloveds for freedom for the generations to come and go. This is something I would still thing about. This is an opinion and sometimes it could be different for different people. The gain and lose in this movie is sad and not fair but it is worth it if you really think about it.
