for the past few years, i've observed that i have a lack of empathy, sympathy, and remorse, and i act on impulses. often, when reflecting, i find myself that i try to move the blame to someone else when something is clearly my fault. i can lie as fast as i can blink without feeling guilty or bad about it. cheating comes easy and sometimes, i even found myself encouraging others to do the same if they want a good grade on a test. a few days ago, my friend, A, told me she had a crush on someone else in a group chat, B. A told me that she really wanted to tell B since she liked him for two years, but didn't know how and already knew the outcome of the situation. out of impulse and thinking it was funny, i sent the screenshots to B, telling them not to tell A that i sent them the screenshots. while doing this, i was laughing. needless to say, i didn't feel bad about doing this at all. yesterday, she told me that person B told her that i said something about her liking person B. casually, all i said, basically, was that she wanted him to know, she was going to tell him anyway, and she already knew how he would react. i told her that i did all of the hard work for her and he reacted the same way she wanted.   


anyways, as the example given and the explanation on my issue, should i see a therapist or try to talk to someone about this? i know all my friends, except for the ones in the one group chat i mentioned earlier, act the same way as we do. we are dark jokers, harsh jokers and don't see when we are in the wrong (usually). we all have hard times apologizing. is this an uncommon but heard of thing? i don't really know what to do, nor what to really say. person A blocked me, which i still feel no remorse and laughed about it with my friend, and moved on with my day.
