Hi Yash,
The early church held this view and they said that God put the curse on man and creation so that sin wouldn't be eternal. I think once Adam ate from the tree and learned evil all men would have to die. To answer your second question, yes, I believe it is necessary that the Christian turn from sin. I'm not saying one will be sinless but I believe there needs to be an effort to turn from sin.
Regarding your question about those in 1 Cor. 15. I think the answer to your question is in a general statement. I think it is a general statement that says, man must die. I believe there can be exceptions to the rule. Paul tells us that Enoch did not see death.
KJV Hebrews 11:5 By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God. (Heb 11:5 KJV)

So if there's really an exception to this rule that "man must die", it has to be because another one of God's rule/law clearly supersedes it. I would see Enoch as this example too but there's disagreement as to whether or not he actually died. So I'm going to look in scripture for (I don't know) another example outside of Enoch (and Elijah); maybe a commandment or verse that may testify to this exception...if such exists.
