Perceptions of conceptions

"Good", "bad"...what is one without the other? We couldn't know the meaning of "good" without the "bad" and vice versa. These two coexist and that can never change. But, all in all, these words, these concepts have a different meaning for each of us. My "good" isn't necessary to be your "good" and my "bad" isn't automatic yours too. There are as many shades of these as leaves in a tree. We do what we subjectively think it's "good" while that "good" may be "bad" for the others. Let's take a simple situation for example:
A poor man needs money because he's starving and he has a wife and 5 children to feed at home. He sneaks out at the back of a tree to pursue a women taking out money from an ATM. He follows her to a less populated area and steals her purse. He gets home and buys food for his family. Now let's think: Yes, he has a problem and that problem is worse if it's not only his but his family's too. Yes, he did a "good" to his family but that "good" is "bad" for the lady he took the purse from. My question is why take the easy way and make others suffer? Those money could have been the ones that the lady needed to pay her rent. So, our man took her money for the rent to buy food for him and his family. Let's look at this from other point of view. Yes, he is poor and his story is worse than the lady's, but if he was poor from the beginning...why did he have 5 children and not only one? What was he thinking to have all those babies when he wasn't able to feed himself, not to mention the whole family? Other point of view may show the lady being very rich and not care too much for her loss. What our man did is still called stealing and when the money is gone he'll need another so he'll steal again. If we're thinking strictly to our poor man, not only that he's doing a "bad" thing to the lady, but he's doing one to himself and his family too because he might get caught and brought in front of the law. So, isn't that "bad" for everyone at the end?
I'm not judging anybody...just thinking logically. I know it is hard to get a job when you have a whole family to feed, a broken roof on the top of your head and not too much "school" in that head. But still I think you can find a job if you really want to. You just have to look carefully for it. I'm not talking about a lawyer, a doctor or an engineer job, but a janitor or window cleaner or something that brings money in a home. There are courses that the state give to the unemployed to learn how to do a job and that is completely free. I'm just saying that there are better solutions than doing "bad" stuff to get where you want/need.
So...we do have also "good" and "bad" inside of us...but we are the ones who choose which one to let out. Usually it is a matter of morals and ethics but also conscience, I think.
