morals and values

Morals and values are subjective - the law decides what is immoral and what is not. Every person also has their own ideas too, but, because of the way our society works, we no choice but follow the regulations that law places, wether 或者 not we believe in it.

Just trust your own instincts, but keep your mind open. (Meaning respect that other people will have different morals and values)

You're allowed to approve of whatever 你 want to approve of, whether it be tipping waitresses, murder, 或者 donating to charities.
But also respect the law. I have many morals and values that don't completely correspond with the law, but I realize that this does not give me special privileged to disregard them.

Just keep that in mind and 你 should be fine.
There are no truthful 或者 untruthful morals. There are only morals 你 choose to have and not have.

Morals and values are always in the eyes of the individual. Therefore, can have them. What they might be is also dependent on the individual, so there's no standard. Most of us can agree on a few of them here and there, but even with those, we often find quite a bit of small disagreements.

The first 问题 你 asked, though, is 更多 interesting. "What is truth?" Truth is a myth. There is no truth. The fact is that the only way that right and wrong are decided for a large group of people is 由 a set of laws, which could result from a religion 或者 a state. And even those can conflict. We like to think that the moral code we follow is what's most correct, and the state 或者 religion of which 你 are a member always loves to perpetuate that belief so that 更多 people can be like them.

Simply put, a concept of right and wrong is just that: a concept. There is no hard and fast right and wrong.

The different ideas about morals and values have always been there. The internet just makes it possible for people to put it there and give his/her opinion.

Morals and Values are subjective, meaning 你 decide whether what's right 或者 wrong. Of course not in that literal matter, but like when 你 see a kid crying because it accidentally dropped his 冰激凌 and 迷失 his mom, do 你 buy it a new one and then help it find its mom 或者 do 你 help it find its mom so she can buy it a new one?
Either way it's both correct in my opinion.

It's complicated, I know =P
But mostly 你 just have to listen to your gut feeling.

Moral change with time and culture, so I stick to religion, not 流行的 and slightly archaic but none the less mostly consistent
