Why doesn't the Guardian Angel defend us from the attacks of the evil one?

Don Amorth replies:

The Guardian Angel suggests to us how to overcome the attacks of the evil one, otherwise; and if we obey the Guardian Angel, we certainly never obey Satan. The Guardian Angel suggests good, the devil suggests evil. Who is referee to decide? Our will! God created us with free will, that is, with the ability to do good or bad, that's why if we do good we have merit (if we were forced to do good we would have no merit), if we do bad it we are to blame, because we must not do it! The Angel assists us, defends us, but cannot prevent us from being subjected to temptations, so much so that Jesus in the garden prayer tells us: "Watch and pray not to fall into temptation". Vigilance is up to us; escape from opportunities, listening to good suggestions, reading good books, seeing good things. What is it that ruins so much youth and not only youth, but also the old and sometimes even priests and religious? Television and the internet. It is you who choose the negative programs, driven by curiosity, despite the Angel's suggestions. Many times we sin because of curiosity. From the beginning when the enemy tempted Adam and Eve, what did he say to Eve? "It's not true what God told you, it's not true that if you eat it you will die." Today he wants to convince us that it is not true that Hell exists. You too have heard from ordinary people, priests and even cardinals that Hell is empty, that Hell is not eternal. It is very important, fundamental to have clear ideas concerning our eternal personal destiny. The Angels suggest good to us; we must listen to the voice of the Angel who suggests the ways of God to us. The Angel cannot prevent the voice of Satan. Satan is there and Jesus himself was tempted by him. We are all subjected to the temptations of Satan; the choice depends on us, it is up to us to choose the right way.
