There is also this from God:
"why will you die, turn from your way and live for I take no pleasure in the death of the wicked"
Ezekiel 33:11

G-D will forgive any sinner who sincerely repents, even on his deathbed.
However this verse refers only to people who have sinned against G-D by not following His commandments (such as, not keeping the Sabbath, disbelieving the Truth of the Scriptures, and so forth).
People who have sinned against other human beings by committing murder, theft, indecency, cannot receive forgiveness from G-D until they have first begged forgiveness from the victims of their sins.
I agree with you, although I have no loss over Arafat's death and his wicked ways, I don't beleive it's up to me or Children of GOD to dance in streets like Muslims who do not know the loving GOD in heaven. Arafat will now stand in Judgement of GOD and GOD will do with him as he sees.
