Any answer you get would be from people who only experience earth, whether they are a wizard or not a wizard.
It sounds to me as if you already know that there are people who have a strong conviction that magic-users including wizards are all evil and go to hell, never to heaven. If you let that convince you without comparing your own experience and thinking for yourself, then the wizarding way is not for you.
I believe in reincarnation, which can make a heaven or hell out of earth. The traditional image of a wizard comes from Western ceremonial magic, many lineages of which are theurgic...making "wizards" actually holy people. There are many views of this to consider. Decide for yourself.
Since wizards are dark witches and almost all witches believe that Heaven and Hell are all around us all the time and not a specific place that your "soul" goes then the answer would be no, but they don't go to Heaven either. Most witches believe in an afterlife or reincarnation.
It doesn't matter what you label yourself, be it witch wizard or whatever else you think you are. (Note I said think). What it comes down to is your belief and your view on a heaven and a hell. I personally don't find comfort in believing something that has no logical backings up to. That is my choice.
Belief holds a lot of power over people and influences them to do both good and bad deeds. If you believe in heaven, sure you could go there. Who's to stop you from believing that?
No one knows what happens to us when we die. It's all best guess and belief.
Witch, wizard, warlock, mage, it's just a title [though most don't use warlock as its an insult] the thing is, while most witches/wizards follow a religious path that teaches magick, there are those who are atheist who follow witchcraft, as well as people of various faiths who cast. If you are a Christian witch, or follow a path that believes in heaven, then yes it's possible. [There is a quote in the bible against witchcraft so speak with your spiritual leader] but the majority of pagans do not believe in heaven so they wouldn't because to them there is no heaven.
No one knows for certain what happens after death, so if you worry about heaven, try some soul searching and speaking with a spiritual leader for guidance. Personally religion is personal, everyone has different views, so talk to your spiritual leader, but ultimately listen to your heart.
