Rajasic is best. Accept this, and then be Sattvic

Nature works on balance, and there cannot be excess of good or bad. Or Nature has to crumble. So there have to be war and atrocities for good to exist. That just Is.

Practical applications?

• So while the Tamasic destructs, and we can seek him and destroy, and that perhaps just what the response intends it to be, we end up spending money confining and trying to reform him. 
• The Sattvic is pure, morally high, but in self-righteousness and stubbornness causes a lot of inconvenience, to say the least, to those around him. This is why those who carried on the crusades and burnt independent women branding them as witches, didn't feel it was wrong. That is why the caste system and anti-conversion mindset flourished, and stopped the spread of Sanatana Dharma, the most profound of teachings, at its very tracks.
• The Rajasic thus is the one most in tune with nature. He follows his senses when the time is right, while again keeping pragmatism when dealing with work. He will kill the Tamasic and provide for the Sattvic too. He is the true ruler of nature, verily acting per the rules the Universe runs on. He will follow, and achieve, based on the four ashramas in life.

Let's take the burning of the Khandava forest in the Mahabharata as an example. And let's keep aside the obvious indulgent holiday and hint of orgy that preceded before it. At the other end, let's set aside the mythology of Agni's demand (even if we set aside the question of whether that demand, or the acceptance thereof by Krishna and Arjuna was morally correct). The fact remains and Krishna and Arjuna, standing at the two extremes of the forest, burnt it down. And even did not let any of the living beings escape from it, shooting them them, leaving them with only the choice of running back to the forest. Then also, these are both heroes. Arjuna, who chose a 12 year vanavas over letting cattle be stolen on his watch. Or Krishna, who selflessly assisted the rise and Pandavas. 

Or watch the movie Unforgiven, and try undersand why the villain's really the villain, he himself can't believe it in the end!

We can sit and wonder and spend lives trying to understand why things are the way they are. And yet, if you simply accept, you could spend your time better indeed.

And then again, that you should. My whole point is that one must accept the balance, and strive towards the good. Denying unless we are ready is not the solution. And that's why reincarnations are needed. And yes indeed, the ultimate goal is to be the Sanyasi who truly realizes and merges with the Self.

Also realize that this Yuga has to end; Nature has to destruct. So to be Sattvic is not wrong, indeed that's how we should strive to be. But the true Sattvic is the one who first accepts and not the one who claims the moral high ground to enforce!
