this is about human nature, not good and evil.
human nature is to be inclined either towards good or towards bad.
You used the words "behave" and "act" which are dictated by good and bad personality which in turn tells you either a person is following good or evil.
Why does one need automobile when he can use his legs to cover the distance?
When a person can use his own legs to cover the distance than why he needs to purchase any automobile? One can ask the inventor, manufacturer that we have the legs to walk than why you invented automobile? Even though we have some animal like horse and camel etc., for such purpose. Manufacturer/Inventor's answer would be that he invented/manufactured for easiness, relaxation. Moreover, None asked him that we have horse and camel for such purpose than why do we even needs for automobile, learn how to drive it in a specific way etc., attend driving center and give test to obtain a driving license etc., ? Manufactuere/Invetor manufactured/invented automobile on his own power and will. None question him why.
As explained above, The Almighty God is full powerful and what He likes, wish, desire He just do that. His creations needs to worship Him same as one who needs the license to drive, attending teaching class for how to drive etc., The manufacturer/inventor invented automobile even when he was fully aware a person can use his legs and/or animals for such purpose, but he invented.
Lastly, if automobile is purchased by some1 than he pays the amount to that person who manufactured (created, invented) hence the 'God' don't ask neither needed anything from yours money.
"need" <----- here's ur clue.
God didn't need to create anything so why did he?
ur example above is about need and invention. man needed the automobile he just didn't make it out of the blue or boredom. it is striving for better at best not creating things for fun or some ambiguous reason.
Hi kali billi how r u? I’m talking you almost after 3 years.
I made a point in my example (2nd para) that; why man ‘needed the automobile’ when he had other means of rides i.e. horse, camel etc.? let me repharase my words. Please tell me "How" the very first idea of creating, manufacturing, or inveting an automobile crossed the mind of a creator, manufacturer, or inventor?
The answer is in the Book (Holy Quran)but frankly speaking I feel uncomfortable whilte quoting the reference (verse) here that is why I given the example.
