You have forwarded a premise drawing the analogy from the boy who called wolf, and proceed to offer case1 and case2, which you say has appeared in the news.

I hope I am presenting my thoughts on why I am asking for citations well, but just in case, let me give you an analogy situation.
Me "Sharks are aggressive and will hunt you down if you enter the water. There have been cases where it happened"
You "Are you sure? Where did you learn this?"
Me "I saw Jaws, the shark hunted down the people in the boat!"

Now, I don't doubt this is what you feel happens like the boy who cried wolf, but I have to ask you to cite your case1 and case2, as I feel this clouds your final conclusion like my paragraph above. Start with the facts, and then the discussion happens about it, otherwise you are discussing an imaginary situation.

As for the boy who cried wolf story itself, I think you are reading too much into it. Fables are simple tales to put forward a point. So the general consensus is that the story is about lying, but if you want its also about taking advantage of kindness, or if you want it is also about together we are strong, alone you're not, or it is also about if the boy had planned better he could have saved the flock. See my point?

The examples you cite didn't happen. Well, the first is true in that Malaysia does not have a "good samaritan law", but when has that kindness been taken advantage of?

The second ..... ah well this is The Sun reporting a Facebook post from 2023 as if it is real news. Would you take some random TikTok from a stranger and report as if it is true? I know many would, but you should rise above that gutter mentality. Still does not mean it happened though.

Maybe just ask your question directly without the pseudo deep-thinking karmic analysisLet me ask you this question - Do YOU really not help people because you fear you will be taken advantage of? Or is there some other reason? Let's start with what you think first to begin the discussion instead of you presenting a situation and asking people to discuss it.
