>what makes the soul immortal
Nothing, it is not immortal it is able to be killed and destroyed for both animals/fish/flesh and humans see revelation 16:3
>And the second angel poured out his vial upon the sea; and it became as the blood of a dead man: and every living soul died in the sea.

Well the soul has something to do with the animals ability to breath as all flesh has the breath of life and thereby a soul. But the spirit which is different then Spirit is neccessary to worship God see john 4:24
>God is a Spirit: and they that worship him must worship him in spirit and in truth.
You also need a spirit because of 1 corinthians 2:14
>But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
And also since you can't spiritually discern to recieve the fruits of the Spirit in galatians 5:22 without having a spirit they in the flesh cannot please God see romans 8:7-8
>Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
>So then they that are in the flesh cannot please God.
This goes back to what Jesus says in john 3:5-6
>Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
>That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Since the wages of sin are death romans 6:23 you need a spiritual body to please Jesus in order to save your soul. See hebrews 10:39
>But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul
This all goes back to the having eyes to see and ears to hear thing because of 1 corinthians 15:44
>It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
The angels in heaven are similar to us that are christians, just being ministering spirits as we are to be ministering spirits to other Christians on the earth.
hebrews 1:13-14
>But to which of the angels said he at any time, Sit on my right hand, until I make thine enemies thy footstool?
>Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
TLDR; animals have souls revelation 16:3 and humans have souls genesis 2:8. But only humans as far as I am aware because of john 4:22 can have a spirit in order to worship/serve God in spirit and in truth.
This is actually a topic that really messes people up because they don't take all of this into account and then read 1 corinthians 15:38, romans chapters 9-11, and galatians 4:21-31. Also if you don't use only the KJV to look up these verses it will make no sense amongst other things.
