A Question of Ethics?

Lately I have been pondering the concept of morality. I don't mean in a religious sense, but more on a common sense level. I have noticed that people's idea of morality is extremely relative. I find this fascinating. Now, I am no philosopher, but could this disparity be simply a part of the human experience, or merely a failure of society?

In other words, do we knowingly do immoral things because we don't fear the consequences, or because we honestly don't know it's wrong?

You may be thinking, where is all of this coming from? Well, it seems like we are hearing cases everyday of someone who gets mad because he (or she) doesn't like their situation, how they have been treated, etc. and decides to go on a rampage and kill the first people they see (and later, themselves).

Does anyone else see something wrong with this? People can be really awful to one another, yes. But does that justify killing innocent people? Not sure how the morality of that adds up. It makes you wonder if some are truly born without a conscience, or if we as a society are making excuses for jerks who can't deal with the inevitable disappointments in life.

I am a firm believer that you are ultimately responsible for your actions. To use a religious reference, you reap what you sow. But don't these mass shootings that end in the perpetrator's suicide make you just a little angry? Almost like they will never pay for what they did. In my opinion, that is pretty low.

Is there any way to prevent these horrible shootings? Maybe not. But I can tell you that it definitely makes me want to be a little kinder to strangers (and loved ones for that matter). Even if it doesn't make a difference, at least I tried.
