I THINK I'M RIGHT BUT CAN'T BE SURE

I think I'm right but can't be sure 
The answer to peace is certainly not war
I think I'm right but can't be sure 
People should not live outside a shop door 

I think I'm right but can't be sure 
It's wrong to be greedy by wanting more
I think I'm right but can't be sure 
Love should conquer all and not be a chore

I think I'm right but can't be sure 
Animals should live and not killed by the score
I think I'm right but can't be sure
It's best in this life if you don't break the law
