First of all, QM Hichens was not an officer. By the way, it is Hichens, not Hitchens.
Secondly, The situation was stressful for all concerned but Lightoller took no greater burden upon himself than anyone else. True, they all did their jobs, but some better than others. In the aftermath of the disaster, Lightoller, being the senior surviving officer and off-duty at the time of the collision, found himself in a position of getting most of the attention, not all of which was providential or coincidental. Pitman left the ship early and kept a relatively low profile afterwards, Boxhall was on duty at the time of collision and had questions to answer about his navigation etc and so it was all Lightoller and to some extent Lowe who made the headlines, especially in later years. The laughable portrayal of Kenneth More in Lightoller's role in the 1958 film A Night To Remember is an example.
You are welcome to hero-worship Lightoller till the cows come home (and even afterwards, if it pleases you), but that does not make him a hero. No way.
