you don't have a malicious heart based on how you are describing yourself
we are all capable of doing foul shyt even if we are decent people but there are people who only see other people as some assets or some level of the playing field as if they are stuck in school games
the amount of times I've seen people fake a persona only to get information out of you after they have gained your trust is disgusting
I've had people tell me very personal things because they trusted me enough with the information without me asking
I feel there is a bond formed when that happens if someone feels comfortable enough to tell you something personal that means they value you in some way
unfortunately there are a lot of wolves that take advantage of basic human interactions
I rememer back in college there was a group of friends who I thought were on that friends for life ish only to find out they absolutely hated one girl and she had no idea. Too cowardly to say anything to her face while calling her a lifelong friend and going out of their way to make her feel like one the duplicity had me dumbfounded

it's sad but it is an outcome I see over and over again
