So I have tried all day installing forge, First I tried on the regular Minecraft Launcher, After installing Forge I tried launching Minecraft w/ Forge Mod, Only returns some errors in the log. And now I just tried with the "MultiMC" launcher and it still doesn't work, These errors came up in the log - http://pastebin.com/a1eEsVty Is it a problem? Or is it just the new Minecraft thing that ruined Bukkit also ruined forge?
Okay, I think I had a similar issue and resolved it, but let's try a few things first.
1) Do a clean install of Minecraft. In your profile, choose the version you're going to use with Forge and run Vanilla Minecraft at least once to get the files Forge needs. (if it's 1.7.2, set that in your profile and run the game, no need to start a new world, just loading until the menu is enough)
2)Download the latest version of Forge for the version of Minecraft you set in your profile. LATEST, not Recommended. This is one of the things that resolved my issue. Run the installer and watch to see if it downloads its libraries successfully. If it does, start the minecraft launcher and select the new Forge Profile it should have made.
3)If it crashes on startup, it should generate a fresh crash report. Find it in the crash report folder and attach the entire text file. Hopefully, it doesn't crash, but if it does, I'd like to see if it's doing what mine did when I had issues.
Once you install you need to choose profile.
Please send log of minecraft error, not MultiMC.

I was going to suggest that next. I don't think Java 8 is meant to work with older versions of Minecraft.
