Is there much difference between these two sentences?

Hi everyone,

Could you tell me if there's much difference between these two sentences:

He always goes out of his way to help others.
He will always go out of his way to help others.

Thanks a lot in advance!

Both sentences has the same basic meaning.  He is a helpful person.

The first sentence is a general declaration of what a helpful person he is.  The second one means that NO MATTER under what circumstances, he WILL do the same thing to help others.  Thus the 2nd sentence contains more force and conviction.  "Will" is a future indicator with very STRONG emotions attached.  

Using "shall" means that he is under some law or force.

"May" means iffy

"Should" = under obligation.

"ought" = under responsibility.

"would" = depends on his mood etc.

He always goes out of his way to help others.
He will always go out of his way to help others.

The first sentence is in simple present tense, which indicates that the sentence is always true (i.e. have been true, is true, and will always be true).

The second sentence is in simple future tense, which is true in the future, but is not necessarily true in the present.
