Knowing everything and allowing evil

[genkaus]

Like I said, I help then because they need it. Because I'm the only one who could at the time.

You don't understand causation very well, do you?

Here, there are two events.
1. Someone needs help.
2. You help them.

You seek to establish the first as a sufficient cause of the second. It is not. There is a gap, since someone needing help does not necessitate you helping them.

So either there is a reason in between, i.e. something that connects the two, or your decision to help them is irrational. Which is it?
