This is not considered responsible. After all, he seems to have never gotten along with Scarlett, and money can only make up for a small part.
Yes we are in total agreement here.
It is a sensitve topic, since it mimics a bit my situation, let's set the scale: not asuming the responsability would be getting lost,
and give a damn about Scarletts alimony and college,
Edmond, at least asumed parenthood and paid alimony, and secured her college tuition, (there was a hint that the Mother would have spend that money too.) the fact that he thought about it reflects that he cares at least a bit and feels some kind of remorse.
for what or many reasons he didn't take an active role in her education and don't tried relentlessly to get in contact with her
we don't know, nor the whole story in deep here, most likely the Mother cut of the contact between him and Scarlett.
To be a "present father" (like me) implies to be on good terms with the mother, and be actively involved in the life of the child,
giving both emotional and finacial suport, love and protection.
that makes him not an total Asshole but also not a good father.
