Because of jewish compulsion and vice for committing the most evil acts they can against the gentiles. Their lives are defined around it. Whichever jew has the highest score for atrocities against gentils, they become the head jew.

Which "Symta"? There are at least 5 different versions of the language. First was written in C/C++, others in Common Lisp, but featured different syntax and semantics (i.e. some supported continuations, others dont)
