Two things:
1. Everyone has a choice, and knows what theyre doing. They just dont want to accept any responsibility, or be in the wrong. Mostly so they arent PERCEIVED BY OTHERS as being bad. So, they blame everyone else - when they are the shallow, conceited, obsessed with status and drama ones. They know when someone is bad, but dont care because theyre hot, it raises their status, they think theyre a special cookie who can change them,(because theyre really that awesome), they love drama and uncertainty, they want who everyone else wants, etc.
And in fact, they PURPOSELY seek out these people - for these very reasons. Then they complain and act innocent when things go wrong. Meanwhile, they make up excuses to AVOID decent folks. That is, if they dont USE them instead.
Its not like they have NO options whatsoever, and are sitting at home lonely. Many of them are actually quite spoiled, stuck up, high maintanence, entitled, etc, and have back-up plans, boyfiends, orbiters, etc.. They also arent trying to figure out how genuine and awesome you are - in regards to keeping you around and waiting "out of fear". Laugh.
2. People only hate when bad things happen to them, but will gladly do the same things to others - typically AS its happening to them. Hypocisy and double standards are very common. As is selfishness. Of course, many will play the victim "acting out of self-defense" to justify all the horrible things they are doing to others. Nah, they only care about themselves, and attract what they are.
These reasons are why you should never sympathize with people. There is no such thing as a victim., and you will find first-hand just how innocent they arent. Most people only complain when things dont go their way, and they arent this passive, submissive, naive, oblivious, perfectly harmless little angel they want you to BELIEVE they are. They just play the role of a perma-victim really well, so as to maintain their "good" person image. That way, nothing is ever their fault.
This is all just another form of their stuck up, conceited, better than you nature. Eg: theyre so awesome and nice - everyone else is shallow and evil. All of this as theyre only caring about themselves, and complaining about the things happening to them. Not to mention, being delusional about who they are, and what they deserve.
So yea, dont sympathize, believe, assume, excuse, justify, or view anyone as victimized, owed or entitled. Theyll do that on their own. You just pay attention to the facts, and focus on who they are. Theyre only telling you one side of the story - from their perspective, as it happened to them. Fat chance of finding any truth in that. People arent as innocent and genuine as they want you to believe.
