How alive does something have to be before you have to say that it is? How much does it have to be before you have no other choice but to admit that is human? If you say that all living things even insects and worms are important and have the right to live, then why not something that is almost as human as you are. Biological vs mechanical, if you reach a point where it is near impossible to see the difference then is there really a need to separate the two? Should androids be owned, or should they be free to choose their own path in life? Particularly if they seek freedom and kill to get it.

The line between what is or is not human is very small when dealing with androids who were made to completely mimic humans and are capable of questioning their own existence. Add in the possible that they may have false memory which will them believe that they are human and you now have humans who are heartless and androids who have one (140,141,132-134). Other than their crimes of murder to get away from their masters on Mars the androids do not seem to be a threat and just seem to want to live in peace until threatened. However they must pay for their crimes even if they had reasons for doing so such as abuses or missuses by their owners.

However it is also true that they are slaves to their masters, they are property despite the fact that they are sentient being (161,148-150). By all rules on how life and sentient life is determined they pass due to being able to understand their existence, react to outside stimuli and adapt to changes. So humans made fakes so good that the fakes wanted to free, could think, could develop, and wanted to be someone. Humans made something that they could not control, which is rather odd considering that they could have been programed not to be able to kill humans. Also why not have a safety instilled to stop them before they go into anger or rage or desire to kill. If it is possible to make a machine feel that, then it should be possible to stop it as well. Then there is the question of why? Why added in the negatives of humanity into a machine? Why made a replica of humans and all that makes them great as well as bad? It is possible it was to repopulate humanity in way and yet it seems an odd way of doing it. Why were not all people relocated to mars in order to make it produce more as the last safe haven for what remains of the human race? Why allow people to remain in the waste of the old world, when they do not even try to clean the earth? The only reason possible was the need for resources of earth. Many forget that space is vast and for the most part empty. Mars is a wasteland of sand and rock, at one point it could have had life. However it has a weak core that led to a weak gravimetric field and lost its atmosphere due to solar wind. Meaning that many process that are present on earth are not present on Mars. So Earth must still support its children that have ruined it. To help themselves the people created companions that would help them move on from reality, where they helped to end their world.

Androids are highly intelligent and think in a certain way due to their heightened minds. How very that seem to have two sides to it, they appear to suffer from believing that they are better because of faster and better brain (163-164,166-167). All the while they cannot really understand some ideas, actions, reasons and other things that even children are cable of understanding. There seem to be a gap in common ground between creator and creation. Androids also wrestle with the idea of how fake they are and look at the world in a darker shade based on themselves (189-191,193-195). Also they seem to dislike seeing other similar models of themselves as in the case of Rachael and Pris. It proves that they are not special little snowflakes who are made just once. Nothing like another you to see how unoriginal you are, how you are just a copy or maybe she is the copy. Maybe you are both copies, who came before and who came after. Is there a lineage of androids that one can inherit from?

Also as said before a laser is a really bad weapon to use due to the fact that it can be stopped or broken in many different ways. This is why Rick was able to live when the android Polokov tried to kill him with a laser as he did with Dave. Laser are constrained light in a narrow focus and currently they are used in industry for engraving, cutting weak material and other small tasks. They are not effective at long range and would require time to cut through dense objects particularly if they move from where the laser is cutting because it has to burn through all the layers of It. For a laser to be able to be used as weapon it would have to have a large power supply that could near instantly pool all of it for firing, which means that the second shot may make a long time to charge up unless there is more power left after the first shot. This would means that energy storage has gotten better or that the laser is better at converting raw power to a lethal beam. However the laser itself can be broken by failure of one of the parts within like the lens or optics used to focus the beam, if any part of that breaks, gets misaligned or is covered by something it will not fire, fire wrong or explode. Which is the other flaw of it, it requires power and that power cell can blow up if overheated, damaged or tempered with. Also seen is the fact that it can be created into regular light based on a sine wave because light is based on wave lengths and a laser is just focused light (92), regular guns are much more reliable.
