Evil Taints

Doing something bad for a bad reason is bad
This we all understand
Stealing for greed is never okay
No matter where the rational may land

But doing something bad for a good reason is bad too
Though many try to justify
Robin Hood was still a thief
No matter how hard we want to deny

Then there is doing something good, but for a bad reason
Many people fall into this trap
Helping someone so you get something from them
Is still wrong you stupid sap

Only when you do the right thing for the right reason
Will your action be just and true
For what you do is just as important
As why you did it too

For evil taints whatever it touches
To be truly good, a deed must be pure
No becauses, no if-then clauses
Of this I am completely sure.
