Feeling after being beaten

Ok din update for a long time, I will continue my teaching story sometime later to make and ending.
Before that, I have heard a story from my friend when washing cloth just now, so felt like blogging it because there are many kinds of feeling arose after hearing that damn story......
Ok it was like this. There were 2 very good friends, I will name them A and B here.
One night, they just walked and talked randomly and happily from outside to A's room as B wanted to borrow something. Then, they met a bunch of drunk people like......5 to 6 people. One of the drunk people asked A and B angrily : Hey, what the fuck are u looking at?!!!"
Then A and B said nothing. They didnt really look at them also actually, just because they were heading to A's home so need to head that path, so they ignored the drinker. Then the drinker started to rush towards A and gave him two to three punches on the ear. On the ear because A avoided to be punched at the middle of his face. Then B tried to help of course, he yelled at the guy and said we're sorry. What he ended up ? He ended up beaten by the drinker as well 4 to 5 punches at the ear as well.
Then the drinker satisfied and they left.
There was a taxi there and several passer-by, they only asked A and B are they ok AFTER the drinkers left!!
Ok, maybe u dun feel a thing after reading this.
But I felt really unfair for them after hearing the story.Many questions started to arise in my heart.
Those drinkers are really a bunch of MOTHER-FUCKERS!!!
First of all, why they beat innocent people?
Secondly, why B need to say sorry?
Then, were A and B's action's appropriate, jz let them beat the fuck out of them?
Final questions, who can help them in that situation?

I really dont understand those questions.....Perhaps there is no correct answer. There were 5 to 6 drinkers, so in terms of ....maybe body size or number of people A and B are not in an advantage. But B din do wrong, so I dun thk need to say ok or sorry to them. Their action of not fighting back perhaps is appropriate, but I just felt really not worthy for them. what's wrong with B trying to help but he got beaten up as well.Sigh...
What will happen if the beating continues longer??
Then what will happen to A and B?Maybe is their fault to go out late at night, but what about the passer-by there?They just sat back and watched as if this is just a DAMN MOVIE!
NO ONE CAN REALLY PROTECT U IN THIS CASE. that's what I figured out.
U either RUN, or got BEATEN UP, or FIGHT BACK.
Well, weigh out the advantage of each one.
If the beating up continues, they really need to fight back, or else they maybe injured badly or even DIE for NOTHING!
The world now is full of bastards.................
Feel really sad after hearing that story...............Quite emotional..........Feel like kick those people's ass myself.........
But what will I do if I face that myself?
I dunno.....but really, do be careful!
let us salute B for trying to help his fren, A......Yea, at least, friendship still exist in this world which let u feel something warm though...............
