It could be something like:
"While I understand Mary Shelley's opinion, and agree that scientific knowledge can sometimes be risky, I believe it is always better to engage in scientific exploration and discovery. I think that knowledge that might seem good, can become dangerous in different context, and viceversa. Therefore, the fear of knowledge being misused should not stop exploration. Moreover, even though some knowledge might be dangerous in the present, it might make a good contribution to the future. Finally, we can never know what it is that we will find at the end of research, so if we stop ourselves before we reach a conclusion out of fear, we could miss discovering something positive. Therefore, I believe that scientific exploration should always be carried out."
