The problem with the concept of good and evil is that to know good you must have an awareness of evil. I AM doing the "good' thing therefore that is the evil thing. As a result your experience of good is always tarnished by this.
Good and evil has to be looked at over time. What is evil today can be a catalyst for good in the future. It is a just a link in the chain.
Healing cannot truly begin until you have the dark thrown in your face so that you can't ignore it. It is the kick in the arse to take action. "I change or die, I can't live like this anymore".
 9.11 is the most graphic example. It is difficult to argue a case anything other than evil for it. Tjat moment in time put the planet into a state of anxiety. It was tangible. It was in the air. This is where it gets interesting. That fear vibration had such an impact on the magnetic grid that Gaia responded with the earthquake and resulting tsunami that killed in excess of 200,000 souls in south east asia. Another seeming tragedy that dwarfed the efforts of 9.11. Gaia flexing her evil muscles? Anything you can do....?
 And yet. this may not be so far fetched. Gaia was in fact flexing her muscles. muscles bulging with the collective fear of the planets population. A quarter of a million lives were sacrificed at that time. Lives that already had a use by date. Lives that were aware of the potential of dying in that event before incarnating. 
The consequence of this event was global co-operation at a level previously unknown. We united as a population. That unity has continued and has propelled us to the gateway of a new renaissance on earth.
There are reports daily that the "dark forces" stranglehold on earth is crumbling. Over time they have been responsible for their own demise.
So good and evil? That all depends on you.

Love, however, asks for no compromise.

Love begets love begets love begets love begets......
