i think if they're gonna mess around with genes, then they should do it for a real purpose. not try to enhance any human features like intelligence or eye colour or anything like that, cos there's always a chance it could go wrong.

by real purpose, i mean they should do shit to cure genetic diseases/disorders before they try to do any of that other stuff.

i can imagine any child who is a decendant of a rat, would not be in the least interested to know where he/she really came from. it would damage them. it's bad enough when people find out they were conceived because their mother was raped.
