Wouldn't the people who are inadequate be the ones who are deserving of help themselves?

And no, they aren't shirking their evolutionary imperative nor abdictating their humanity. There would be millions of people deemed to no longer be human based on their incapability to help others... and if someone is inadequate at helping others, then they are unable to help themselves. Which means that people who can't help themselves, aren't human, and why should others help them? Sorry, but your logic is driving me in circles right now.

But that does not make me inadequate.

People who are unwilling to help others are douchebags, but people who try and aren't able to? There is nothing wrong with them, and they aren't deserving of hate. They tried.

Many social animals do not always look out for each other - male lions will eat/kill any cub in their pride that wasn't fathered by them, rabbits will cannibalize their offspring, dolphins will harass a pregnant dolphin until she aborts the baby just to have sex with her, etc etc. Those are all social creatures, and those are certainly not instances of helping. Are those animals douchebags too? Sure are! But being social animals doesn't necessitate always helping each other out - humans help out much more than other species do, as we do try to take care of the people who wouldn't be able to survive on their own, and that is not often the case in the animal kingdom.
