I know plenty of Christians that think differently and are still involved in and looking forward to their lives in Christ here. I know some who want to do everything they can in Christ in Spirit and be rewarded as He promises. I'm not sure how you think you qualify to say what every Christian should think or do.
Actually Paul clearly said he was hard-pressed - distressed / absorbed - to make the decision and his clear preference was to depart and be with Christ which he says is far better than staying here in flesh. You don't seem to care much about what the Text actually says.
In the end of these verses he made the decision that the Lord wanted him here to help others grow. But, again, this doesn't mean Paul wasn't opening his heart to his readers.
As was pointed out in the article I offered to you, this was not the only time Paul spoke of such things with some comparative language:
NKJ 2 Corinthians 5:1-8 For we know that if our earthly house, this tent, is destroyed, we have a building from God, a house not made with hands, eternal in the heavens. 2 For in this we groan, earnestly desiring to be clothed with our habitation which is from heaven, 3 if indeed, having been clothed, we shall not be found naked. 4 For we who are in this tent groan, being burdened, not because we want to be unclothed, but further clothed, that mortality may be swallowed up by life. 5 Now He who has prepared us for this very thing is God, who also has given us the Spirit as a guarantee. 6 So we are always confident, knowing that while we are at home in the body we are absent from the Lord. 7 For we walk by faith, not by sight. 8 We are confident, yes, well pleased rather to be absent from the body and to be present with the Lord.
Your repeating "suicide" for some shock value doesn't negate the fact that these thoughts Paul expresses were obviously real and not a one time thing.
Nor does it negate anything Paul is explaining to us re: human choice, which is the real focus.
