I try to analyze world events based on realpolitik. I don't see how it benefits Israel's interest to help either side of the Syrian conflict. Israel may not like Assad. But he is at least a secular autocrat. There is a lot that Syria can do to stir trouble in Israel's northern border, but Assad, possibly fearing an all-out Israeli invasion and a loss of power, has kept the conflict with Israel to tit-for-tat proportions. The Syrian opposition contains elements of Islamic radicals and may be even worse for Israel. My take is that unless there is compelling reason Israel can take advantage of Syria's civil war, its best interests is to sit quietly and let its enemies fight it out among themselves. I don't see how Israel can be bothered to intervene in Syria. Turkey has far more interests in the area, and is politically much closer to attacking Syria than Israel is.
