I'm pretty sure he is more concerned about saving the survivors rather than stoping the viral outbreak.
Although stopping the viral outbreak will definitely be on his agenda I'm sure.
At least he is not going around shooting everything up and willing to do anything at "all costs" like Chris who seems to be willing to let 1000s of innocent people die just so long as he completes his objective.
I could be wrong about my assessment of Chris, but judging by that article that seems to be the case with Chris.
And as for this Jake thing,
How the hell does he have powers?
Judging by his age, Wesker would not have injected the Prototype Virus when he was conceived.
