The Engineer

One would need to possess a wealth of knowledge, mechanics, chemical, biological and structural engineering are required to design a weapon.

I have tried designing a schematic for a nuclear tipped WMD (weapon of mass destruction) - I have the core elements however I know very little in the nuclear field, one of which I don't think I will fully understand without seeing it.

What purpose are you wanting to design your own weapon?

Have you fully assessed the situation; what circumstances changed making you change your mind; did God tell you not to do it or was it your subconscious?

Humans have a basic instinct to survive, perhaps this took over.

More context would be great.
