If you believe that 'good' and 'evil' are fundamental and inseparable aspects of humanity, meaning evil can never truly cease because it's part of what we're made of, then yes, you might believe that balance is the healthier option. Belief in either extreme can lead you to a dehumanizing view of people, and a lot of evil has been done in the world in the name of ridding it of a greater evil, for the sake of an unquestioned good.

A world of "no"; that's a kind of "balance" I want no part of.
Arguably, from that point of view, it's a part of you whether or not you want to be a part of it. Every human life suffers, and brings suffering to others, that can't be avoided. We're limited by hate, fear, greed, hunger, mortal terror, the need to survive and see our children survive, and our own point of view.
But perhaps the center path is itself evil if you refuse to stray from it. That would lead many Western minds to the parable of the Good Samaritan, after all. Who would refuse to feed the hungry because hunger is just part of human nature, or refuse to clothe the poor because poverty is just the result of bad luck and bad decisions?
Well... plenty of people who fall prey to the just world fallacy, but that's digressing.
All of the suffering of Hiroshima and Nagasaki was done in the name of good, and people were slaughtered until it was decided good was done, because the greater evil had to be opposed at any cost, and it was thought to be the lesser of all conceivable evils. But when you oppose evil with evil, where is the good to be found?

I have no idea what message you're trying to convey here. No, none of those qualities (other than survival) are innate, and if you believe they are, you'll do less to stop them. We can be better.
Consider things more abstractly, greed is generally thought of as an evil. Bur trying to distroy it is counter productive, but wuty care it can be useful. The drug war is a great example of taking an ideology past the point of usefulness.
