The sometimes definition of life as being an organism which has the ability to reproduce itself seems harsh
It's not easy to define something that's defined as neither Life nor non-Life because, something that neither Life nor non-Life might very well be an impossibility, all depending, of course, on how one defines LIFE.
Even a single human cannot reproduce itself. The sperm requires an ovum from an other - or, vice-versa..
Viruses can multiply
A virus can die of be "killed" .. cease being a virus.. forced to cease being a virus.
A single-celled animal such as a bacterium is certainly a very basic living organism.
A human is arguably the most unbasic living organism and more to the point every part of the human such as finger or brain make up the whole.
Barring dead cells, all cells and structures of a human which are not dead are by definition alive
An organelle is a subset of a cell; e.g., the nucleus. Based upon the functional behavior of a nucleus, it seems impossible to think of them as non-LIFE.
Semantics of life/non-life aside, the still unanswered question of how a virus replete with genetic information came to be, is of greater interest than various nomenclatura arbitrarily assigned to it
