I believe Usage [closed]

Solution 1:

It's a fairly strong and absolute statement -- he's definitely opposed to murder.

But of course humans can always "weasel word" things: The speaker might still favor capital punishment and/or accept the necessity to kill others in a war.

There are other contexts, though, where "believe" just means "feel" or "suspect". Eg, "I believe the engine has a bad spark plug" -- the speaker is not married to the idea but is offering it as a supposition.

Solution 2:

While "believe" is not the strongest word to suggest one's views and principles, it doesn't imply doubt. It is still preferable to "think" and "feel" which tend to indicate a more fickle outlook. For clarification, use "strongly believe" if you want to indicate a stronger conviction.
