Pluto can not be discarded from the solar system. It was reclassified because we have learned more about our solar system. There are other objects out there in the same region of space that are bigger than Pluto and we do not label them as planets. We believe it is very unlikely that life would exist on Pluto or any of the objects that are that far from the sun. The same can be said for most of the other planets. The most likely places life might exist are Mars and maybe the moons of Jupiter (places where liquid water might exist).

There is no mechanism we know of (short of a large mass approaching Pluto and the gravity pulling it out of orbit) that would cause Pluto to leave the solar system.

Not really sure what "as it is farthest from sun so theres no possibility of life ever" has to do with it being ejected from the solar system.

I don't know who would go to all the trouble to go out there and throw it away. So we will probably leave it there.

It has been demoted in its classification and is no longer considered a planet, this is not because of how far away it is from the sun however, but rather has to do with the definition that was decided on for a planet. Pluto does not fit that definition. It is considered a "Dwarf planet".

No, it has been reclassified as a dwarf planet a new category of objects which will no doubt expand as more are discovered, ans also are the reason for its reclassification. See

and

Life is unnecessary to qualify as a planet.

no. pluto may not be a true planet anymore, it's a dwarf planet like sedna, but just because of that it doesn't mean it will be discarded, we still have a lot to learn about it
