One problem with a PED discussion is that adults have a tendency to apply adult morality and adult cognition onto what is often an adolescent decision. This leads us to make judgements about younger people's behavior that may be a little unfair (BTW -- to be clear, I did not hear anyone in the previous discussion making moral judgments, I'm speaking to PED discussions in general).
I am not surprised when any young person decides to use PEDs because the reality is that the benefits are potentially huge, and the risks/detriments are not immediately experienced. One trait of adolescence that young men in their 20's often carry with them for a while is a feeling of indestructability and imortality, something that aging and reality gradually help to mitigate over time. But, imagine being a 16-17 year old who is enticed by muscles, girls, attention, sports glory, money, college, etc. -- and then encouraged by role models (older kids or professional athletes), and encouraged by sychophants and manipulators who stand to gain their own money or pseudo-celebrity status by associating themselves with the athlete. Then, of course, influenced by the savvy drug pushers who have become experts in how to disguise or cover the use of PEDs and who are often smooth salepeople assuring young 'clients' that they are safe and that they'll be big, strong, etc... Yes -- personal responsibilty is the ultimate accountability measure, but young athletes are easy prey since all the benefits of PEDs are precisely the things that so many young people want.
Lebron is 24 years old and I wouldn't be surprised or even disappointed in him (as if that matters) if I heard he had used PEDs. He's old enough to make his own decisions and to be held accountable, however, I wouldn't judge him harshly. Just my opinion.
