There was never pure Hero, nor pure evil.

As for facing Japanese invasion, Wang started with a much firmer and braver pose than Jiang and Mao, as a Hawk. In history, under those circumstances, history figures behaved with their own best judgment. Some of the actions were beneficial to the society in the end result, we portrait them as Heroes; some actions were harmful to the country, general public label them as evil or "Han-Jian", WHEN IT'S SAFE AND TRENDY to do so. Based on history book, both PRC version, Taiwan version, and Western version, Wang didn't do that for himself, and he knew what he would be facing. Right or wrong, he had the courage to do something he believed was good for China. That's far nobler than those 墙头草。

No, I don't consider him Hero. Heroes are in average citizens who do small noble things just out of good wills.

As for your comment about: 中国文明之所以还能存在并且发展到今天，是因为有无数眼界不如他开阔情怀不如他浪漫的一根筋的人存在。在国难当头的时刻如果不能挺身而出，不如隐居故里，独善其身吧。
I beg to disagree. Personally, I think Chinese culture survived was because it's more advanced and more influenced than others. So invaders adapted to Chinese culture, which prolonged this unique culture. It's never because how brave Chinese are. Historically, Chinese always have more chickenhawks in talk and writing than actual fighters. That's why China was taken by minority invaders over and over and over again. That's why Japan was convinced that they would succeed the same way, and they almost did. I would bet they would adapt and advocate Chinese culture greatly as well if they had succeed.

If there was no 太平洋战争， if there were no nuclear bombs, not sure what would happen to China by now. Maybe lots of people would spend countless money and effort to show their love to 天皇, similar to the way they are portraying how great 成吉思汗 and 康熙大帝 were.
