What is the difference between the examples below?

Generally, in a newspaper, news is based on past tense (things which have already happened). 

Then why are headlines written in ways that says: He Kills (shouldn't it be: He Killed)?

For example:

Parliament passes bill
vs.
Parliament passed bill

Also

He kills his friend
vs.
He killed his friend

Please help. 


Question: When are Unity scripts actually disabled?
Answer: I think this document from the Unity help should be useful. Look to the diagram at the bottom of the page.

Physics and collisions are processed before the game logic so if you disable an object during collision it will become disabled after its next update.
