There was a secondary explosion in the back side of the building that caused the building to collapse. Expert analysis and modeling found that the explosives needed to bring down the building would be more than 4 times what was delivered by the GBU-38.

The U.S. did strike the building and civilians were among the dead. The building was leveled because of explosives that ISIS had put inside. The investigation could not determine whether the civilians were being held hostage in the building nor could it determine definitively whether the building was a storage facility for ISIS explosives or whether it was specifically rigged to collapse.

Warfare is a degraded state of human interactions where lots of bad sh*t happens, but by the usual norms of how these things proceed, deliberate killing of civilians is considered worse than the accidental killing of civilians during attacks against military targets. The former condition is often euphemistically termed as collateral damage. According to the account I'm reading, in the Mosul attack the civilian deaths are thought to be the result of a 500 pound American dropped bomb igniting more explosives owned by ISIS.

There is no such thing as Karma, and there is no universe mechanism by which it would work. No Karma, no reincarnation. Just wishful thinking.

It can't be much of an afterlife if one is annihilated.

Maybe that outcome, if it is one, is the exception rather than the rule. Let's hope. LOL. Further, at least in the Christian paradigm belief there is a "person in charge" of the system, God, making it work. What person or mechanism makes reincarnation and Karma work in asanb's belief?

.
True. Christian annihilationism is a more humane belief option than Lud's favourite of eternal hellfire, in which the dead are resurrected to face Judgement with those that pass the test getting to live forever in heaven or on a renewed earth while those failing to pass muster by accepting Jesus as their personal Saviour or during their earthly lives failing to have presented the approved prosocial behaviours towards those less fortunate are subjected to a second death that results in their staying dead permanently. The UB presents a wordy, bureaucratic version of the doctrine with its "personality extinction" idea.

The Urantia Book does have "personality extinction" but it's more self-inflicted suicide than anything. It has nothing to do with "those failing to pass muster by accepting Jesus as their personal Saviour or during their earthly lives failing to have presented the approved prosocial behaviours towards those less fortunate are subjected to a second death."

And please, don't conflate the Christian slogan of "accepting Jesus as your personal savior" with The Urantia Book.

(37.1) 2:3.3 Cessation of existence is usually decreed at the dispensational or epochal adjudication of the realm or realms. On a world such as Urantia it comes at the end of a planetary dispensation. Cessation of existence can be decreed at such times by co-ordinate action of all tribunals of jurisdiction, extending from the planetary council up through the courts of the Creator Son to the judgment tribunals of the Ancients of Days. The mandate of dissolution originates in the higher courts of the superuniverse following an unbroken confirmation of the indictment originating on the sphere of the wrongdoer’s residence; and then, when sentence of extinction has been confirmed on high, the execution is by the direct act of those judges residential on, and operating from, the headquarters of the superuniverse.

( 37.2) 2:3.4 When this sentence is finally confirmed, the sin-identified being instantly becomes as though he had not been. There is no resurrection from such a fate; it is everlasting and eternal. The living energy factors of identity are resolved by the transformations of time and the metamorphoses of space into the cosmic potentials whence they once emerged. As for the personality of the iniquitous one, it is deprived of a continuing life vehicle by the creature’s failure to make those choices and final decisions which would have assured eternal life. When the continued embrace of sin by the associated mind culminates in complete self-identification with iniquity, then upon the cessation of life, upon cosmic dissolution, such an isolated personality is absorbed into the oversoul of creation, becoming a part of the evolving experience of the Supreme Being. Never again does it appear as a personality; its identity becomes as though it had never been. In the case of an Adjuster-indwelt personality, the experiential spirit values survive in the reality of the continuing Adjuster.

Nor is there any time limit ("during their earthly life" as you said) put on any of this in The Urantia Book. IN FACT, there is no such time limit in the bible either as far as I can see. The time limit, "during their earthly life," is a DOCTRINE OF MEN.

196:0.13 Jesus does not require his disciples to believe in him but rather to believe with him, believe in the reality of the love of God and in full confidence accept the security of the assurance of sonship with the heavenly Father.
