Answer 1

Objectively it doesn't matter, and every human has his/her opinion on it. 

Answer 2

No, it is not a bad thing that all life in the universe becomes extinct. Then again, it is not a good thing either. It merely a process.

Answer 3

Bad thing is you to waste your time with impossible guesses .

Super-health, shiny youth, comfortable wealth !

Answer 4

Good or bad doesn’t come into it.  If it happens, it happens.  If one believes in science the Earth won’t be forever. Everything will die.  The Universe will die and all matter will break down.  What happens after that is pure guesswork at the moment. 

Answer 5

Not really.........................

Answer 6

No such thing is going to happen. According to the Bible at Ecclesiastes 1:4 "A generation is going, and a generation is coming, But the earth remains forever." The Hebrew word ‘oh·lamʹ, here rendered “time indefinite,” basically means a period of time that, from the standpoint of the present, is indefinite or hidden from sight but of long duration.

Jehovah’s will is not for the earth to be inhabited by people who have no regard for its Owner and little love for one another. Long ago he promised: “Evildoers themselves will be cut off, but those hoping in Jehovah are the ones that will possess the earth. The righteous themselves will possess the earth, and they will reside forever upon it.” (Psalm 37:9, 29) 

Answer 7

Good or bad for whom or what? Bad for those who want to keep living? OK, but beyond that, who or what is there to care if life disappears? Does the universe care? We can't possibly know. I say we are an artifact of the universe and if it evolves to exclude life, so be it. Control over such a thing is well beyond our grasp. 

Answer 8

Consider how long it took to evolve. That timeline on which struggle occurred, makes life valuable. We owe it to our ancestors to push forward.
