Is God only for good? Is he not for bad? Particularly when Devil is his own creation?

God is for good as well as for bad.

God did not say "'I am the only God; Whoever doesn't believe me is from Devil". God created us because He loved us, and because He loved us He also gave us free will - the ability to do good or evil, to love Him back or not, to help others love Him or not. In the same way he lets us decide for ourselves, the same way He does not condemn us to hell for doing something bad, instead we choose where we want to go by how we treated and loved and followed Him when we had the chance.

Look at it this way: If you had a child that you loved with all your heart, would you lock that child up in a prison and only let that child do certain things and command that child to love you? No, (I hope not) you would let the child learn to love you on its own and therefore love you even more because he/she exercised that love on his/her own.

You say the devil is a creation of God, and so he is. But the devil was not created evil. Nothing is created evil by God. It is only through the free will bestowed on His creations because He loves us that there is now a devil and a following of other fallen angels.

If a good person accidentally falls from a building, yes he will die the same way but that is where the similarities end. He will not be judged the same way, because he did not have the same intent in his heart as the criminal.

The lion and the tiger are animals, given free will but not a spirit like God gave us. He gave us the animals for our pleasure and to keep us company, that is all. Once you start comparing us to animals, you're losing the idea.

And are we really brought up in a society that says murder is bad and helping poor is good? Thousands of babies die every day through murder and it is labeled a "choice", while many more are starving and dying in other parts of the world because they are poor, and who is there to help them? Not this society, that's for sure. Why? Because there is a significant lack of God or faith in our society that is considered the norm. So before you start making these grandiose assumptions, please analyze what you are really saying.

Listen to eo785. The rosary is a sure way to get to Heaven (if that's where you would like to go), if it is prayed faithfully and fervently.

Wrong again. Let me explain to you what circular reasoning is:

You Christians take the Bible to be God's word and the ultimate authority, so tell me why I should believe in Him, but don't use the Bible.

As to your question, it has the same answer as the last 10,000 times it's been asked - capacity for choice does not equate to evil. Your parents didn't want you to be this way - you chose it for yourself

the devil is a useful tool nothing more (without his persuasion Jesus would not have been crucified)

The devil just tempts....people choose

all evil in this world comes from the heart of man

my stance with God is that God is good and bad. I believe God punishes me for every little mistake.
