how can someone do it?

I saw a video yesterday where the man was beating his mom and sister's for property. I have seen many videos and news about it. People beat or kill others for property or money.

Why? Don't they believe in their destiny? you will get what you have in your luck even if you don't do these thing's and if they aren't in your luck then you can't have it even if you do these things.

They don't love their love ones? How can they do things like that to their own family. We can't even think about it. They aren't human's. They don't have humanity or heart.

There are still people who love other's. Who do so much just for stranger's and there is people like these who don't have humanity also exist.
