If L is your list
(Delete[L, #1] - L[[#1]] & ) /@ Range[Length[L]]
gives you the result.
Example
In[3]:= L = RandomInteger[100, {5}]
Out[3]= {63, 59, 75, 17, 99}
In[4]:= (Delete[L, #1] - L[[#1]] & ) /@ Range[Length[L]]
Out[4]= {{-4, 12, -46, 36}, {4, 16, -42, 40}, {-12, -16, -58, 24},
{46, 42, 58, 82}, {-36, -40, -24, -82}}
