It seems that only Kantian ethics would support gene editing and overall, i would also agree with the rest of the ethical theories and reject genetic engineering. For many years molecular biologists have been looking for using cellular repair processes to intervene and modify DNA of organisms by guided genome editing; thus is, to change the organism genome by introducing a new function or correcting a mutation. In the last years CRISPR/Cas9 has been chosen as preferred method for genome editing due to its high degree of fidelity, relatively simple construction and low cost. These characteristics make this technique attractive to be used by any molecular biology lab, but the problem is that can be used for any purpose unless be regulated. It is because of this wide range of very contradictory risks gene editing would not be allowed by many theories. in my opinion, CRISPR has its advantages and disadvantages ranging from ethical concerns to being known as the fastest, cheapest and most precise way of editing genes. This scientific breakthrough has the ability to eliminate diseases, solve world hunger, provide unlimited clean energy but can additionally get out of hand very easily. CRISPR has potentially given us direct access to the source code of life and at the same time given a great amount of hope to billions of people.
