Atonement

I am only putting down my thoughts and some people might get offended. I am sorry

1. Can Jesus atone the sin of Christians by sacrificing himself?
2. Was Jesus a suicide bomber who kills himself so that others get the benefit?
3.What about people who lived before the time of Jesus - Abraham and Moses died unatoned.
Can we imagine these two prophets going to hell?
4. Why did God sacrifice His "son"? God who has so much power need not resort to sacrificing
His "Son" in order to get a job done
5. Is the sin atoned for limited to that of the Original Sin only? What about other sins like invading Iraq for instance or telling lies about WMD
6. Since the Original Sin is a myth, Jesus is in fact atoning a non-existence sin.
7. Is there any part of the Bible that says Jesus has been given the authority to forgive sin?
8. Forgiving sin is the prerogative of God. Only He knows the circumstance how a sin was committed.
So only He can evaluate the deserving case.
9. Sin is the outcome of breaking God's rules and no body can accept repentance on God's behalf.
God has not relegated this authority to any body. Relegating authority means weakness on God's
part. and God is not so.
10. Is it possible that atonement is a scheme devised by early church leaders like Paul to get the
pagan Roman to accept Christianity? Sort of blackmailing?
