"The Devil" doesn't have a human form, cause form limits the content, and we know that the devil is more capable than a human form.

There're devilish people among humans though, top of my head thinking of people who killed the most in the last couple of years (for a fact) Bush comes to mind.

Answer:

Satan tries to trick people into worshiping him. (2 Corinthians 11:3, 14) One way he misleads people is through false religion. If a religion teaches lies about God, it really serves the purpose of Satan. (John 8:44) People who are members of false religions may sincerely believe that they are worshiping the true God. But they are really serving Satan. He is 'the god of this world.'-2 Corinthians 4:4.False religion, spiritism,

and nationalism mislead people

4. Spiritism is another way Satan brings people under his power. They may call upon spirits to protect them, to harm others, to foretell the future, or to perform miracles. Satan is the wicked force behind all these practices. To please God, we must have nothing to do with spiritism.-Deuteronomy 18:10-12; Acts 19:18, 19.

5. Satan also misleads people through extreme pride of race and the worship of political organizations. Some feel that their nation or race is better than others. But this is not true. (Acts 10:34, 35) Other people look to political organizations to solve man's problems. By doing this, they are rejecting God's Kingdom. It is the only solution for our problems.-Daniel 2:44.

Resist Satan by continuing to learn about Jehovah

6. Another way Satan misleads people is by tempting them withsinful desires. Jehovah tells us to avoid sinful practices because he knows they will harm us. (Galatians 6:7, 8) Some people may want you to join them in such practices. Remember, though, it is really Satan who wants you to do these things.-1 Corinthians 6:9, 10; 15:33.

7. Satan may use persecution or opposition to get you to leave Jehovah. Some of your loved ones may become very angry because you are studying the Bible.

It depends on what you define as "the Persian religion" and what you define as "the Greek religion".

Persian Religion: Islam | Greek Religion: Greek Orthodox Christianity

However, the current main Greek religion is Christianity. Refer to question below for the similarities between Islam and Christianity.

The main similarities are:

1. Both are widely believed religions.
2. Both believe in God's angels.
3. Both believe in the last Day of Judgment.
4. Both believe in Paradise/Heaven and Hell.
5. Both believe that no one enters Paradise/Heaven by own deeds/merit but rather by God Mercy and forgiveness.
6. Both believe in eternal life after earthly death.
7. Both forbid adultery, robbery, unjustified killing, cheating and lying.
8. Both religions are similar in practicing mutual respect to their believers. Quran says (meaning English translation): ".... You will find the nearest in love to Muslims those who say 'we are Christians'. That is because amongst them are men devoted to learning and men who have renounced the world and they are not arrogant. And when they listen to the Quran revelation received by the Messenger (Muhammad), you see their eyes overflowing with tears because of the truth they have recognized. ... So because of what they said, Allah (God) rewarded them ...." [Quran, chapter 5, verses 82-86]

Persian Religion: Zoroastrianism | Greek Religion: Ancient Greek Mythology

Zoroastrianism and Greek Mythology have very few similarities, like multiple gods and demigods and a belief in prophecy.
