Lets face it, betrayal hurts, even when you get to know a person for a long time and you give them your trust and then one day they deceive you, figuring out one day this "friendship" they built with you was just a cover up to benefit their own agenda in a destructive way.
People can be ruthless sure, and there are many people that will lie and make an attempt to crush you just to get what they want. Just know that you always have to be ten steps ahead. We have all been betrayed at least once in our lives and its not a good feeling. Do the culprits Reconcile with the ones that have been offended ? that is on their own accord.
I could go on and continue to be poetic about this topic, but I will leave you with this one very important moral: Looks can be Deceiving
