I get the cynicism; it’s easy to feel like the world is just full of uncaring people sometimes. But, does adding one more help?
Evil is in most cases a Yin/Yang system of abuser and willing victim. Both are dependent on each other for their common goal of creating evil in this world.
The abuser from primitive motives: "I have to do it to them, because if I'm not an abuser, somebody will make me a victim."
The willing victim because he thinks it's an easy path to be a good person: "I don't have to engage my heart and soul, just take abuse and each "point" of abuse turns into good boy points for me."
There is nothing to be admired about victims and the victim cult is a mistake. They deserve empathy and help, they don't deserve admiration.
To stay on topic:
You definitely are not going to be invited to my parties!
Taking care to not be an abuser and to not be a victim is rather the best path, even if it demands more from the person. It's easy to just do what others tell you, but it will soon bring misery.
"I'll be nice, and others will be nice in turn" is magical thinking. There is no such deal in place.
It's perfectly possible for others to soak up all that niceness and then suddenly leave without being equally nice in return. If pressed, they might even say they didn't ask for the goodness that befell them, they were just happy to accept when it was offered, thereby absolving themselves of any obligation.
