Truth be told it looks possibly repairable.
That worst pin, use a needle to bend it back straight.
Start from the end of the row under the other pins to lift it up, then use the point from above to line it up with the stub on the package.
Scratch the pin gently to get a bit of fresh metal.
Put a little flux on it and the stub.
Cut a short bit of solder and leave it sat waiting on a heat mat.
Use a scalpel blade to gently hold the soldered foot of the pin. Do not move, do not slip, do not wobble.
While holding the foot with the scalpel, clean your iron, the. Touch the tip to the cut piece of solder so there is a small amount on the tip, wipe it onto the broken pin and lift the iron away in one movement. Assess.
Did you join the break? Did you bridge to other pins? If it isn't perfect, hold the foot with the knife again, put a tiny bit more flux on the location and touch the iron to it briefly.
The really important thing is don't let the pin move too far. You need to keep it still with the knife. Best I'd the foot end doesn't get hot enough to melt, so speed and not too higher iron temp is ideal...
Or find a new chip and solder it in. Make sure you get a new chip with straight pins. It's a pain if they've been bent.
No harm in trying to fix this one first though
