I do need help to understand what kind of evils like mara are there in buddhism.

hi Daniel

in buddhism, the word 'mara' means 'killer' and refers to the 'killer' of the spiritual life; the killer of peace; the killer of goodness; etc

the word 'mara' has the same linguistic roots as the word 'marana', which means 'death'

just like in the Bible, Mara or Satan, can be both internal ignorance or an external temptor

for example, in the Book of Job in the Bible, Satan was an angel sent by God to torment & test Job

similarly, it seems in Matthew 4, Satan may have been external, as follows:

Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. The devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. “All this I will give you,” he said, “if you will bow down and worship me.” Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’” Then the devil left him, and angels came and attended him.

generally, in Buddhism, Mara was like an angel that tormented the Buddha & his disciples, as follows:

these links come from sections 4. Mara-samyutta and 5. Bhikkhuni-samyutta at this link

as for Mara being internal ignorance, internal craving & internal attachment, there are many quotes from the scriptures by Dhamma Dhatu, also from the Samyutta Nikaya, at this link

good luck & all the best
