Let's simplify the given expression step by step:

Given expression:

$-5 \left( -5 \left( -2(5 - 3) - (3 - 5) \right) + 5 \right) - 5(5 - 2)$

Step 1: Simplify the innermost parentheses

Start by simplifying the expressions inside the innermost parentheses:

$5 - 3 = 2$ $3 - 5 = -2$

Now, substitute these values back:

$-5 \left( -5 \left( -2(2) - (-2) \right) + 5 \right) - 5(5 - 2)$

Step 2: Perform the multiplications

Next, calculate $-2 \times 2$:

$-2 \times 2 = -4$

So the expression becomes:

$-5 \left( -5 \left( -4 + 2 \right) + 5 \right) - 5(5 - 2)$

Step 3: Simplify inside the parentheses

Now, simplify $-4 + 2$:

$-4 + 2 = -2$

Substitute back:

$-5 \left( -5(-2) + 5 \right) - 5(5 - 2)$

Step 4: Continue with multiplications

Now, calculate $-5 \times -2$:

$-5 \times -2 = 10$

So the expression now is:

$-5 \left( 10 + 5 \right) - 5(5 - 2)$

Simplify the addition:

$10 + 5 = 15$

So:

$-5(15) - 5(5 - 2)$

Step 5: Simplify the remaining expressions

Calculate the value of $5 - 2$:

$5 - 2 = 3$

So the expression is:

$-5(15) - 5(3)$

Step 6: Final multiplication

Now, perform the multiplications:

$-5 \times 15 = -75$ $-5 \times 3 = -15$

So the expression becomes:

$-75 - 15$

Step 7: Final addition

Now, add the two negative numbers:

$-75 - 15 = -90$

Final Answer:

$\boxed{-90}$
