Lying is justifiable if it's for the greater good.  It depends on the situation.  But I can see how it is useful.  If some won is going to get hurt really bad for no reason.  Like if they have a different religion then a lie can be used for the grater good by saying that you don't believe in God.

Sometimes violence is the only way to solve a problem.  I just Strongly agreed because I felt like it.  what if some won pulls a knife on you?

and you have a bigger knife and no cops where around to help you?  Than you scare your enemy with your knife or a gun if you have one.

It is okay to kill someone in self-defense.  What if some one was about to kill you and no won was around.  Then pick up a rock and bash him in the head.

Words are stronger than fists.  The pen is mightier than the sword.

Bullies hurt others because they have low self esteem.  I know a bully that docent care about him self.  

Only the best and brightest students should receive the best education to become a nation's leaders .  Well maybe   I think it depends on how the parson is smar.

Revenge is never justified.  I think it can be justified to sone dagree.

Crying is evidence of weakness.  Not only it is a evidence of weakness if your seen you will get bullyed the rest of your life.

Any action is acceptable in war.  No what if someone just desided to nuke a place with civileans like in WWII.

Teenagers need discipline and rules because they can't control themselves.  only some not all.

Only through personal sacrifice can someone create positive  change.  I think that is true.  I dint know what else to say.

Generating compassion for your enemies is the only way to create peace.  I can see how that is true.
