why there are some bad qualities

Why people try to do something wrong, i 

was just figuring it out

Because some people does something wrong

and they become defensive try to protect themselves

so they start reacting the same way to others 

Instead at the very first instant just ignore 

and never repeat what others are doing

to few others,

then the world will not have any bad qualities

Its a good habit to follow to be such a way which you dont do that hurts you, to others,

then the world will be having good people together living with harmony. 

Example

Gandhi faught to bring independence to India,

Godsey killed Gandhi who freed our country 

thats the difference in thought patterns which makes or breaks..
