I wouldn't say necessarily hate... e.g. guilt or stubbornness to preserve themselves can come out like dislike.
I used to not put much interest into other peoples hidden motives and stuff - I genuinely didn't care or well, I would focus on
why they have that motive and what could be hurting him/her because I knew it had nothing to do with me, e.g. I or someone else was just in their way.
Whatever people say or do only reveals what's within them.
I would in some cases tell my closest friends though because they're rather quick to jump the gun when someone is mean or could be perceived as mean lol but, I would tell them or even bicker with them so they wouldn't judge the person and get assy with him/her, and understand where the person with assy-ways is coming from. I mean, there is only room for one ass at a time lol

And, there is no need to use their hurt against them, it does nobody any good.
If you can know their hidden motives you can equally know what's hurting them. We've all been hurt and getting a random help is better than needing to deal with everything alone.
Anyway, Ironically, many of those that had hidden motives have turned into becoming good friends of mine, And my friends have embraced them.
I was basically really naive
or something prior to getting PTSD.. I just wanted everyone to feel good and be friends. It even might have been selfish or I might have felt useless if I did, I don't know.
'You' don't have to become friends with that person but we are all people with souls in the end of the day, we all get hurt. Sometimes our hurts come out in unconventional ways but in the end of the day nobody wants to feel hurt.
...However, lol, after getting PTSD I do put at times interest in hidden motives and I find that a shame. I don't want to but "there are" dangers everywhere now

and I can get really quickly paranoid. The shitty part about it is that I still know what's going to happen! But I can't always tell the difference between knowing if it's a fear response or an intuitive one.I only know though what is what if I calm down, take a step back and try to feel what's hurting them. Then it gets clearer but sometimes.. eh.. that gets forgotten and I turn into an ass. Kind of have learned lately just to give people a free pass and try not to project my own assy-ways onto them. If I do then I need to tell them.
The world can be a shitty horrible place but it's honestly up to us to make it better. Not the next person or some twice removed cousin of a friend of a friend.
okay rambling over

but the moral of the story: we can all be asses at times, give the benefit of the doubt.
