To attack someone you must feel justified in doing so, as though it is what you believe in, is the right thing to do, and therefore becomes a decision you make based on the conclusion you've come to about what is happening any why.
But this merely indicates there is a lack of awareness of the whole truth. The person's mind must have a block to the awareness of love, which is causing them to mis-perceive and mis-believe and come to false conclusions. A lack of information is producing errors, and justifications based on this seem sensible but are mistakes.
No-one in their right mind would ever attack anyone. No-one aware of love would have any justification for anything other than love. Those who attack do not know what they are really doing, to themselves or to others. They are blind and unconscious. They are insane.
All attacks are mistakes. All wars are mistakes. All violence is a mistake. All blame is a mistake. There can never be any true justification for any of these.
Given that anyone believing in attack must be unconscious, insane, not in their right mind, and unaware of the fact they are hurting themselves, ALL attack is forgivable. They simply do not know what they are doing.
This is why Jesus taught to "forgive them for they know not what they do." In other words, EVERYTHING is forgivable, including you.
