Bare with me here and follow again.
Then your logical basis for justfiying your claim that the Bible doesn't actually have a complete picture of Hell (loosely termed Eternal Damnation in your OP then clarified by your definition "eternal suffering") falls apart.
You made the claim that the Bible doesn't have a complete picture of Hell (i.e. Eternal Damnation). Which is actually a double claim, just like your OP is. It actually has a hidden, yet unjustified, claim being made within it.
That is, that YOU know what a complete picture of Hell is, such that you can compare your known/accurate complete picture of Eternal Damnation (i.e. Hell) to what the Bible says about it. i.e. YOU have the truth about Hell in order to know whether or not the Bible's version is false. (Which, by the way, you don't really have the truth/standard by which to compare it to the Bible.)
In order for you to be sure and accurately claim that the Bible does NOT, in fact, have a complete picture of Hell, it is absolutely/logically necessary for you to have a standard by which to measure the Bible's claim to. You don't have any, other than the Bible's version, of course. At least not one your gonna find members here to agree to.
When brother
FreeGrace asked you; Then who does have a complete picture of Hell? your reply was that you didn't know. Fair enough. You could have simply retracted your claim then and corrected your logic.
But you didn't and went on to say that it (the truth about Hell) cannot be found in The Bible and you know this because we all here argue about what The Bible says about Hell (Eternal Damnation).
Then I called you out on that particular justifying reason for rejecting the Bible's version of Hell (or what God's Word says about it) as well by asking you the question; If we stopped arguing would you believe God? Since you now say no, then that's not really the reason you think God's Hell is unjustifed now is it?
You now admit that even if we didn't argue over it, that wouldn't really change your view on the completeness of God's version of Hell (Eternal Damnation) either, right?
My point in all this is that if you want to find out the truth about whether Eternal Damnation is justification, yes/no? (Your OP title/question) you must think logically about it and look at valid logical arguments. Oh, and it's necessary to first define what you mean by Eternal Damnation. And for that matter, justification.
If you define Eternal Damnation as Eternal Suffering (as your first reply seems to), then you are going to find some Christians that agree with that definition and some that do not. It's been in debate since the 2nd Century. But any progress toward justifying why "Eternal Damnation" is necessary/justified (in your mind) simply cannot be made without first defining what
you mean by Eternal Damnation accurately and precisely. Or at least getting agreement between you and your debater(s) on a definition of Eternal Damnation. [which is why it's NOT off topic to be discussing and providing evidence for/against the definitions; Eternal Damnation = Eternal suffering versus Eternal Damnation = Eternal Destruction.]
I, for example, do not agree that Eternal Damnation has a Biblcally based defintion equivilent to eternal concious suffering. Some here do think God's Eternal Damnation is defined as. eternal suffering. I think (as do a few others here) it's Eternal Destruction, Eternal death, Eternal Perishing, etc. and or capital punishment after all non-saved people face their creator for judgment that Biblical. And I can see good reasons/justifications for that definition.
Might I offer a suggestion for your continuing OP thread's progress (or lack thereof); Pick
your definition, that you can agree makes the most Biblical sense (or for that matter just what you see as the most justifiable), for Eternal Damnation (now that you've seen some of the arguments for/against Eternal Suffering) and then ask people that can agree with
your definition; why is that type of Eternal Damnation necessary/justified?
If you pick Eternal suffering as your definition of Eternal Damnation, I'll just simply bow out (and maybe other like minded posters will as well) of this thread and you can get justifications/reasons for that view of Hell from people that agree with you and your definition.
If you pick Eternal Damnation = Eternal Destruction, then I can provide reasons why that's necessary.
Make sense?
