For those unfamiliar with Bogota, it is a high altitude airfield in a 'bowl', surrounded by high terrain. Departures even on all four engines, require careful planning and precise flying. I think that there is more to this accident than just one-engine out - let's wait and see before criticising crew procedures and maintenance. As for old engines not producing the rated power, that's a "red herring"! I don't think that the a/c would not have been up to max. permitted weight(for the conditions) for a flight to Miami, so there should have been some reserve left to cater for the engine out case.
