Remember the root of his name, felos de se. No matter how it is cut, Felo is a root for evildoer. Here is a legal definition of felo de se.
A felon of himself; a self-murderer. To be guilty of this offence, the deceased must have had the will and intention of committing it, or else he committed no crime. As he is beyond the reach of human laws, he cannot be punished. English law used to inflict a punishment by a barbarous burial of his body, and by forfeiting to the king the property which he owned and which would belong to his relations. The charter of privileges granted by William Penn to the inhabitants of Pennsylvania contains the following clause: 'If any person, through temptation or melancholy, shall destroy himself, his estate, real and personal, shall notwithstanding, descend to his wife and children, or relations, as if he had died a natural death.
Another: "Felo-de-se" is a Latin phrase meaning "evildoer upon himself," or, simply, a suicide. In England before 1870 a distinction was made between a suicide, which was the name given to an act of self-destruction committed by a person of unsound mind, and a felo-de-se, which was committed somebody who was sane. If a self-destruction was judged a felo-de-se, the deceased's estate was generally forfeited to the crown.
