I don't understand what you are trying to convey. I main jungle. From what I understand, if I was in this situation:
The jungler is probably stronger than me, so I don't cross the river to prevent being called out alone.
If I spot a winnable fight or gank, I take it.
Top lane is probably feeding. Helping the winning bot lane push goes into our win condition rather than help top try to fight them off and feed them even more, playing into their win condition.
It is not trolling, it is strategy and common sense. You have no power in this realm!
