Etymology: Your spelling, "fectless," is an older variant of "feckless," and the story starts with "feck." That word is a shortened form of "effect," which in Scots and northern English came to mean something like efficiency, vigour, or worth. Someone who was "feckless" lacked that force: weak, ineffective, or without the capacity to achieve anything. The "-less" ending is the ordinary English suffix meaning "without," so the original sense was close to "without effect." The word's moral tone came later. Over time, "feckless" shifted from describing a person who was simply feeble or useless to one who was careless, irresponsible, or lacking in purpose, and that sense is the one most common today. The "k" in "feckless" is a historical spelling that has stayed in standard use, while "fectless" survives mainly as a variant spelling.
