Israel is no more evil than the United States is. Israel is no more evil than the United Kingdom is, or France, or Germany, or Russia. And it's certainly no more evil than Syria, Egypt, and Saudi Arabia are. You don't have to support Israel or Palestine, but cheering for war against Israel is hypocritical and stupid. If you want peace so badly, you will not fight for peace through means of destruction; instead, you will approach it patiently and allow cooler heads to prevail, which they will in the end. In the mean time, rather than antagonizing one side and apotheosizing the other (whichever pairing you may choose), you will put them both on the same level and agree that they both have the same right to peace and everything else as you do living in a safe and developed nation.
That's directed at a lot of people. Don't take personal offense, just think about it.
