Does Torah require circumcision on the 8th day for gentiles?
Torah requires it ONLY for those gentiles who wish to participate in Jewish life.
New Covenant scripture discourages it.
Ex 12:48 And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
Why did Abraham circumcised himself, his sons, and his servants?
IN order for anyone to participate in the Passover [Yeshua's offering] circumcision is required.
Want to because it is a kingdom loving thing to do.Correct. But under the New Covenant gentiles do not have to be circumcised or keep passover.

Understood.
Permission to do so but it is not an obligation.
Abraham was gentile.
Yes indeed. Exodus is after Genesis, Abraham was told to become circumcised, even before they left Egypt in route to the promise land. Abraham participated in a ritual with Melchizedek.
