There's a jump instruction by an address read from RAM, a bit flip occurred so a condition "if friend greet else kill" worked as "if friend rape else kill". Absolutely anything can happen, that wasn't determined by program design flaws and errors. A digital computer is a deterministic system (sometimes there are intentional non-deterministic elements like analog-based RNGs), this is non-deterministic random changes of the state.

In concrete terms - things break without reason. A perfect program with no bugs, if such exists, will do random wrong things if bit flips occur. Clear enough?
